AI

Fixed a bug causing units sometimes to act before the result of the previous ability was calculated (e.g. shooting arrows at dead targets, double-casting CC).

Fixed several bugs causing units sometimes to run back & forth aimlessly

In PvP, the Interference tree now only targets enemy heroes

Only in Caverns will DoT abilities be spread around evenly. In PvP they'll now focus down one hero target.

Archers should no longer melee attack adjacent enemies when they have the opportunity to step back & shoot

Tanks will no longer target stunned enemies with Taunt

Increased the chances for DPS Close units to use Sky Hammer and Slam

Support units now consider groups of 2+ allies (from 3) as a "cluster" for AoE heals

Units will no longer use Adrenaline while feared

Fixed bugs preventing use of XP Potions / Candles from hero inventory

Fixed a bug causing summoned units' puppets sometimes not to appear

Added SFX to Razor Shot and Blunt Arrow
