Crusher stinks, and what is so hard to use about drill sergeant? Just hold B down (xbox) and dash away. Simple, and he wins.
I completely agree, crusher's attack is just not as good as Thumpback's also his landslide doesn't deal that much damage, his ranged attack is probably one of the only things that Crusher is useful for because it gives him a chance to deal some damage however it's range is shorter than his hammer attack (i think) and also his move which launches saws from the earth AKA earth grinder or something does little damage his basic attacks are the only attacks that can deal a decent amount of damage and all of them are slow attacks not to mention he's a giant so he's slow, I think a lot of skylanders can beat him in PvP, especially S2 Chop-Chop
