I heard the quality went down the toilet after the guy who started it died from an allergic reaction to a routine medical procedure, also they fired Vic Mignogna from a voice role after the cancel crusade was launched against him.

Yep, that's what happened to RWBY. Tragic story of a passion project IP with a lot of heart. The battle scenes downgraded almost immediately after Monty Oum died, and when they decided to make a fun Hogwarts-esque setting into a boring quest to save the world, the writing died as well. Then the lesbian shipping finished it off.
