Claymore does work in killing Bolas, and everything else when in short range.
Lances does work in killing everything.
People probably should try it out, nothing funnier than watching 2 Bolas simply disappear, and it gives Hover a good anti-swarm option.
Also it is the fastest riot in the game (beating Ogre), having one of the largest AoE for a riot, a fast turn speed and a decent amount of health at 1300HP.
That makes it have a higher metal-HP ratio (4.3333) than Ripper (4.25)!
