Going to get hate for this because it's DoW II, but Eldar in Dow II are fairly high risk, high reward, and considering the parallels between the two games OKW could feasibly be this. Relic just done goofed.
Pretty much, borderline OP last patch and now they scrabble around the map in 1v1 spamming Panzerfusiliers.
It certainly is hard to balance though since life uh, finds a way. Players will always find the path of least resistance and downplay risks and maximize rewards.
So to balance out the rewards possible for the faction that on paper is supposed to have some rewards other factions don't have we end up with this smudgy, strange faction we have now that has too many risks.
Or the problems of the previous patches where rewards were too great. I still remember trying to deal with vet 5 volks and Obers that killed 2 models with one burst. I don't want to go back to that.
I never played much DoW2 but maybe the balance is possible. Isn't that another Relic game where everyone plays a community mod now since they were not getting the balance they wanted?
