The "flavor of the month" pets get nerfed (some to the point of being unusable) but the shitty pets never get buffed. It just leads to people finding the next OP combo and we're years from ALL pets being nerfed equally so they are all on the same level.
There is literally nothing that makes certain wild pets (cockroaches, snakes, frogs, etc) different other than their name and sometimes skin, Bliz stated they'd rather make new pets than fix the old ones
It's a fun time-killer, though.
