Ranked Matchmaking Officially Coming to Dota2

December 6, 2013

On the off-chance that I have any readers who don’t already know this, the official Dota 2 blog confirmed that the “next major update will add a ranked matchmaking feature to the game.”  As for the listed specifics:

  • Ranked matchmaking is unlocked after approximately 150 games.
  • All players in the party must have unlocked the mode.
  • Currently, only All Pick, Captains Mode, and Captains Draft are available.
  • You may not participate in ranked matchmaking while in the low priority pool.
  • Coaches are not allowed in ranked matchmaking.
  • Matches played in normal matchmaking do not impact your ranked matchmaking MMR, and vice versa.
  • Your ranked MMR is visible only to you and your friends. The MMR used for normal matchmaking is not visible.
  • When you first start using ranked matchmaking, you will enter a calibration phase of 10 games. During this time, your ranked MMR will not be visible.

Nothing too surprising.  I have some concerns about having no group limitations, but if they think they can pull it off we’ll see how it goes.  It’s an interesting revelation that team and solo have different MMRs, but I wonder if that specifically refers to the “solo queue only” opt-in option in current matchmaking.

My biggest potential complaint are the modes.  It’s a good thing they’re limited to avoid splitting the pool, but it’s disappointing to have All Pick and then two modes where you have to trust a captain to draft in an environment where people are likely to complain about “MY MMR.”  I’d feel better about it if CD were more like RD as a middle ground with both pick phases and individual picks, but oh well.

[Skill Build Analysis] Earth Spirit

December 2, 2013

 

We covered Ember Spirit last week, and as you might remember, I went on record as saying that Earth is the more viable hero of the two.  Ember is in this place where he needs an early farm source but doesn’t have an obvious place to get it.  He’s not an especially strong solo laner as a melee hero with a rather risky form of wave clear in Flame Guard and no potential escape mechanism until his ult.  He also really doesn’t warrant an especially protected lane.  He’s like Kunkka in that he has a form of right-click scaling in Sleight of Fist, but a 6-slotted Ember isn’t going to close the game the way an Anti-Mage or Spectre or Alchemist or even a Drow Ranger does.  It’s an awkward place to be in.

Earth Spirit, on the other hand, has been the less obviously successful of the two, but a huge portion of that can be attributable to the high skill cap.  Why do I say this?

EarthSpiritWinRates

A ~4% boost between Normal and Very High is pretty good historically.  Back when I looked at win rate improvements in 6.77, a 4% boost would easily be a top 10 finish on a list largely populated by at least situational competitive pickups.  This is also still very early into Earth Spirit’s release.  Dotabuff still has the hero’s day-by-day win rate trending positively, so it’s reasonably likely that his VH performances are improving at an even faster rate.

But anyway, this post is ostensibly about skill builds, so let’s go over the skills:

EarthSpiritSkills

Those were fun to summarize in limited space.  Anyway, here’s what the usage rates look like:

EarthSpiritUsage

Unsurprisingly, Boulder Smash first is the most common build at all skill levels, but are Boulder Smash builds the most successful?

EarthSpiritBuildWinRates

Well, yes and no.  Broadly speaking, Boulder Smash builds are the most successful in Very High, but the margin isn’t huge.  The most successful primary-secondary combo is Geomagnetic Grip(E) -> Rolling Boulder(W), but this is also the rarest build, so the win rate is likely just the product of a very small sample size.  The most reliable builds in the bracket appear to be Boulder Smash(Q) -> Geomagnetic Grip(E) and Rolling Boulder(W) -> Boulder Smash(Q).

But where it gets interesting is that Normal and High appear to operate on a very separate set of rules where Geomagnetic Grip(E) is king.  To see what’s going on here, let’s look at another chart where we look at Earth Spirit’s win rate by how many points he has invested in each skill by level 8.

EarthSpiritWinRatesbySkill

Very High behaves as expected.  Maxing any of the skills appears fairly viable, and it appears that having at least 2 points in Geomagnetic Grip (E) by 8 is a significant boost over treating it as a one point wonder.  But in Normal and High, maxing Grip is almost indisputably the way to go.  What gives?

My suspicion is that Grip first is the best ‘training wheels’ build.  If you’re not confident with the hero, E->Q->W is the way to go.  Once you feel more competent, Q->E and W->Q will likely outpace Grip builds in many situations.  That being said, I had heard mumblings of 2 points in Grip early for the extra stun duration being important for certain combos, and the findings appear to support that.

Items aren’t surprising.  Think of Earth Spirit as a dislocation specialist along the lines of Batrider, but with Blink and Force staff being less absolutely necessary.  Some fashion of mana regen on Earth Spirit is common in all brackets, with Arcane Boots being the dominant source.  Bottle and Urn are also popular options.  Aside from that, he can pick up whatever utility items the team needs, with possibly an extra emphasis on survivability items like Mek and Shiva’s if you’ll likely be needed for 5v5 initiations.

Finally, I had received some questions about Earth Spirit’s farm priority, and I did a little looking into it but don’t feel ready to release anything.  The XPM tests are still experimental, and they don’t really mean a lot without other heroes to compare it to.  What I will say is that so far, Earth Spirit looks surprisingly level dependent, in the vein of a 2 or 3 position in comp Dota terms.  I don’t think that this proves that Earth Spirit cannot function as a support, but it might be sketchy to run in your average pub compared to other more versatile support options.  Mid or Offlane are likely the most reliable options for Earth Spirit in a low coordination environment, which is again similar to Batrider.
