Is it so hard to switch to Citron or Chomper when there are a lot of Scientists

@Boolerex
Well, the Chomper us tough enough to survive multiple hits, he gas the most annoying stun in the entire game, Spikeweed, which can catch any Scientist after his warp and Burrow. These are pretty good tools to counter Scientist if used correctly. They might require be more defensive, but even then, appart from the Hot Rod Chomper and the Chomp Thing, every Chomper can goe toe to toe with a Scientist if you don't rush head on. (Which is something you should never do as Chomper or Super Brainz)
