Well after blasting past the campaign and diving in multiplayer for about a week of play, I can honestly say that I don't like any of the units in the game. None of them feel great to use right now, they are just means to an end.
Right now the game just feels like spam cheese units until you can amass an A-move army. Picking the race determines the difficulty in doing that. So many units feel like garbage the later in the game you get. All tier 1 units and some tier 2 units mean jack diddly squat. They don't retain any value. Neither do Elites past a certain point.
And why does everything feel like it's moving through molasses? In 3v3 this is torture because unless you are A-moving you are risking getting punched in the ++heresy redacted++ and not being able to do anything about it.
And I know what some people are going to say. You got to use the abilities. I would, if my units lived long enough, were able to move fast enough, not get stunlocked, slowed, etc, before I could do that. There is too much casting ++heresy redacted++ in this game. I get that this is more what DOW2 was about, but I hated that aspect of the series and I really hate it here where the units are not even half as charming as they were in the second game.
