Developers at Valve have been continuously on their feet since the deployment of Patch 6.86 for "DOTA 2" and as proof here comes Patch 6.86b in barely a week's time.
As previously reported, "DOTA 2" Patch 6.86 has temporarily removed Death Prophet, Faceless Void, Lone Druid, Riki, Doom and Winter Wyvern from Captain's Mode, as the abilities of these six heroes have been significantly reworked. On the bright side, their absence from the Captain's Mode won't take took long as these six will be returned to Captain's Mode in a succeeding 6.86b/c patch. Valve did not give players the chance to miss these heroes because Patch 6.86b has just been dropped.
The previously missing heroes are now back in Captain's mode, with the exception of Riki. According to JoinDOTA, the ominous and sneaky stealth assassin, got the most buffs from "DOTA 2" patch 6.86b. Other than the return of Death Prophet, Faceless Void, Lone Druid, Doom and Winter Wyvern, patch 6.86b has nerfed the mana cost reduction of the Arcane Rune. Another notable change includes buffs to Arcane Orb and Astral Imprisonment for the Outworld Devourer while Pudge might be sad that Meat Hook's Aghanims Scepter damage has been nerfed.
As indicated in the Patch 6.86b patch notes, the rest of the changes include:
-Spirit Siphon duration increased from 4 to 5 seconds
-Arcane Orb Int steal increased from 0/1/2/3 to 1/2/3/4
-Astral Imprisonment cooldown rescaled from 20/17/14/11 to 22/18/14/10
-Cloak and Dagger backstab damage multiplier increased from 0.4/0.6/0.8/1.0 to 0.5/0.75/1.0/1.25
- Tricks of the Trade now only affects heroes
-Tricks of the Trade AoE increased from 450 to 475
-Tricks of the Trade cooldown rescaled from 90/80/70 to 70
-Time Dilation AoE increased from 650 to 725
-Time Dilation slow rescaled from 4/6/8/10 to 7/8/9/10%
-Time Dilation duration rescaled from 6/7/8/9 to 5.5/7/8.5/10 seconds
-Meat Hook Scepter damage reduced from 175/275/375/475 to 180/270/360/450
As previously reported, Swedish Team Alliance dominated the WCA 2015 "DOTA" 2 Championship in a 3-2 victory over LGD Gaming's "DOTA 2" Squad. It seems that Patch 6.86 has played well for Team Alliance
