The countless bugs that have still not been fixed.
The insisting on features that were in the game not being in the game despite communal backlash.
The implementation of several retail-esque features (the MMR system, the game engine, “Epic WG”, Layering, Locked Servers) that were not asked for and have caused further complications and problems.
I can keep going but what you said there is objectively false because not only are the things I’ve said true they are also done intentionally.
