I picked the striders, hulks, and fortresses one, because commamd bunkers and the new hulks are basically just death sentences if you mess up at all, even in heavy armor or wearing a shield. It's not even you're fault sometimes, they just like to aggro from across the map.

The rocket striders themselves, are purely just annoying as shit cause they somehow always spawn behind you on the high difficulties. They dont usually kill you right off the bat, but the ragdoll into something else does. Just feels bad when it happens.
