Warhammer Online: Wrath of Heroes from Bioware takes the PVP element of Warhammer Online and makes it it’s own game. WOH uses the DOTA champion system idea and has you play as various heroes capturing towers and bases. While DOTA is top-down WOH follows from a third-person perspective.
The above trailer shows off the vampire/necromancer Nethys.
Warhammer Online: Wrath of Heroes doesn’t have an official release date yet but there is a closed beta going on at the moment.
