OH, it's a new game! Except it's not...
Fake difficulty is off the scale, and all this release does is repeat the aggravating aspects of the EW3 (such as "hero strength enemy ranged units" and the occasional too many spawns outside revenge run) and gets rid of the balancing strategic features (such as timed spells instead of mana).
It's not a bad game by any means, but it's not worth another entry when there is EW3. I really expected something EPIC.
