RTS campaigns are never good and they never really have been. Most of the time it's either a boring slog with the enemy given some sort of random artificial advantage or it's an annoying mission that has you controlling a handful of units in a way that generally breaks most of the features that make you want to play an RTS game in the first place.
I truly don't understand the people for whom the campaign is genuinely enjoyable.
Sounds like CoH 3 cope to me
The CoH 1 campaigns were awesome
