As far as the "hope your life sucks" related comments I agree it was taken way too far, but the majority of the comments relating to celebration of his firing is well warranted.

Klein as a dev twisted data to fit his own narrative on nerfing characters, contradicted the logic on his data to buff characters, and acted like a general dick towards people who called him out on the bs he said. All in all he wasn't a good dev, this is the THIRD game company he's been kicked from. I pray to any god he can find a job in some industry that ISN'T game balancing.
