Quite frankly I would LOVE the idea of them actually allocating a team to balance everything; however, they have no teams actually doing that... they don't even have a team that's focuses on only PvP; hence why we keep getting stupid "fixes" that only seem to buff the meta of the month. So if they aren't willing to put the resources into balancing, then the only way to fix it is to limit classes to get rid of the metas.
