Wrath of Heroes Beta 3.0.2b-III-()() is running now through Sunday night (8pm EST).
They quietly added a new hero to the mix, a fellow named Albodi.
Albodi is a hulking Chosen armed with a vicious greataxe and the ability to double his target's cooldowns.
He doesn't hit particularly hard but he can cast an area-effect dread-spell that negates nearby foes' chance to dodge. So, he's a tank that can deal with a typical tank weakness - the untouchable Korelei the Witch Elf. The problem is that he appears to me to be way too much of a one-trick pony and just doesn't compare at all to Bax the Black Orc's toolbox (long knockdown, sprint, big self-heal, burst damage + survivability).
I'd try to get some more time in with him, but I really can't stand the new map they added and that's all I've been getting queued for.
