The fact of the matter is that while there are many things that don't work in the tabletop and need changing- like the ranger's class features- plenty work fine or at the very least aren't immediately apparent as being problematic in a game. We have sweeping changes for no reason, like why are spears and quarterstaves no longer versatile? No one thought these weapons were OP in the tabletop and did too much damage, yet they were changed for the game and we don't know why.
Effectively, we know the tabletop is mostly balanced. If the game started from the rules of the tabletop and then tweaked from there based on player feedback I think plenty of us would be fine with that. Instead, we have a mishmash of changes and bugs that mean we have a harder time fine tuning the balance.
