LoL is not balanced no game is balanced
One does not simply compare LoL balance to iRO balance. Just because the "ideal" state of perfect balance cannot ever exist, does not mean that everything which isn't 100% balanced is equally trash. I'd say Riot does a good job balancing, or trying to balance, compared to most other game companies.
Balance is for the game designer to consider. The players are the absolute last people who must affect this. If x change was deemed fine by the devs, then it is their decision to push it through. Some design choices have certain tradeoffs. Maybe they think the reward is worth the cost. The only complication is that iRO is not the same as kRO, and iRO does not have a team of its own which can analyze and objectively decide.
It's a great thing to listen to the community's wishes every once in a while, especially when it is unanimous and the said wishes do not harm any other member of the playerbase. But giving such wide power to players, and taking certain key decisions simply because certain people or number of people wanted that change on forums, even though other players opposed it , is just favoritism and arbitrariness on behalf of the CMs.
