blob is way too vulnerable to chems

[Vitatroll]

That could be remedied in a number of ways. A large bit of blob-fun is evolving and adapting, so more of it wouldn't hurt. Two methods I can think of right off the bat:

1) Increase evo point gain but decrease upgrade potency. Far easier said than done, especially with non-passive abilities.
3) Allow blobs to respec by devouring nuclei or if they're smaller than x number of tiles. They may or may not be able to grow another nuclei by growing y number of tiles
