I think venom is also scaled... so it only leaves info shots and ties (And ofcourse viruses).
But ties and info shots should be enough to handle anything I've seen so far. Being small is still a big advantage, and it also allows for greater numbers which is a very big advantage, should probably nerf the eyes on small bots or something like that if you want to balance it out. TieFighters stays small and has an attack that uses ties only to kill oponents, and it works against any oponent I've tryed it on, but only if they're not moving too fast, which is why it also acts a bit like pacifist once below a certain amount of nrg to give people shell and slow them down.
And Excalibur is my favorite bot to test against... it's stable and simple and usualy performs well. It was also one of the bots with the best defence against pacifist (Just pushing a value into .up through the tie to bring enemies closer), multiply did better though, because it was focusing on -6 shots, and the thing they both had in comon was killing enemies from a distance which is why they never got within venom range of the pacifist. This is also why I saw it as a chalenge to kill Excalibur only using ties... and TieFighters manages that, but it uses info shots and venom along with it's tie when killing alge, but onyl on alge though (This can also be a problem if facing oponents like pacifist which makes shell on the alge to protect them and confuse enemyes)
