I think we can interpret OP's opinion as he believes in its *current* state the game is excellent and it doesn't need any further balance changes. It's his opinion. He wasn't trying to say that past balance changes were unnecessary.
That said, this game has always been more in need of "buffs" than "nerfs". AFAIK, it was always the things that were blatantly underpowered / useless that really bugged players, and not the overpowered things. Since you seem concerned about things getting nerfed too much, I'm telling you, there's no need to worry.
