Heh, y'know, Mothim isn't completely outclassed. It's really the only bug there that has the chance to go completely mixed with 94/94 attacking stats. It has quite a deadly U-Turn coming off of 300+ attack, and it has a great special movepool.
The big problems with Mothim lie in the fact that it is incredibly slow and has an awful physical movepool outside of U-Turn...remember that though. Mothim is probably the best completely mixed bug there.
