Warhammer 40K
There have always been balance problems with Warhammer, especially the fantasy kind, from day one. The game is bent towards Chaos. No matter what, they have the most powerful units in the game for the point cost of a support unit in any other army. They have no weaknesses where other armies do, and excel at any number of points. For example, in Warhammer 40,000 they have everything- heavy firepower, flexibility, close combat ability, speed. Everyone has a weakness, even Space Marines. Space Marines are extremely flexible, but can’t excel at anything. Everyone else has to make up for lack of heavy armor or close combat ability or infantry firepower. It’s just tremendously frustrating sometimes. It almost makes me want to give up the hobby.
