[@ADamnFiddle] Yeep, I guess you can say that they played them...like a damn fiddle. 

Though really, Berserker in general should be like the hardest class to win the HGW just because how much Master-Servant's communication ended up being important in most wars. Caster honestly have little chance to win too since the main targets of the war have MR of varying degrees, requiring more clever maneuvers although thankfully most Casters are capable of that. Assassin is pretty bad tho, since they're usually summoned as one-trick ponies, and assassinating a bunch of masters that have planned for the war for decades aren't just going to work easily. Even counting /GO originals, the best assassins are ones that aren't really Assassins. Like Shuten.

Rider has it a lot better due to having good class passives even if at lower rank compared to >sabers, but they usually compensate it with impressive array of NPs. 

So yeah, HGW is totally rigged and it's pretty fun how subsequent TM works bar extra I think still has the rigged template for the war.
