I agree with everything, removing Merasmus too, like @Bone said. I'd also like to remove Piss Cakehole and BLU Nnggh Sniper.
These bosses always are chosen if the player did not use the !ff2boss command. Like, it's 9/10 chances you will get one of these, and people hate most of these bosses because they are either too bad or too easy to fight against.
For example, I once killed Merasmus alone with a mini sentry, dispenser and a short circuit. His rage couldn't break/deactivate any of my buildings, and the burn damage was nullified by the dispenser, while I stunned him over and over; same thing happens with Phoenix Wright, as his rage only covers the screen and makes a big radius of fire damage. Things like these shouldn't be happening, and I agree with @NitNat 's idea that this is why people aren't playing so much on this server like they used to. We need to implement newer, more fun bosses to play as and against.
At least, that's my opinion.
