The paradox of balancing issues.
We've seen the reworks. Champions being nerfed to balance gameplay. But is this helpful?
This is League of Legends, and Champions are supposed to be "oppressive". They're CHAMPIONS. Riot often releases new champions and sometimes reworks old champions to give more utility to their kit. And whenever a new kit is introduced, Riot will spend weeks or months revising these kits to make them more "balanced". But that isn't very balanced, is it? Again, Champions should be oppressive. If balancing is an issue- our focus should be on the champions being left in the dust. NOT the champions who are brand new, or newly modified.
You see- Riot can only do so much. The effort used in re-balancing "OP" champs takes away from the focus of other champions. Effectively, the balancing issue is never addressed because it is always put off for tuning adjustments on champions that were recently worked with. This creates a relationship of favoritism- where the champions who get attention are guaranteed that attention for further tweaking to whatever attention they just got. Meanwhile, champions who need the attention have to wait because of this ironic, and ineffective priority system.
OP champs are not the problem. They are champions. We want them to be OP, and flashy, and awesome. We just don't want our champions to be pale in comparison to others. This doesn't mean nerf Yasuo's Wind Wall- even though every non-Yas player might like that idea.. It means give us tools to our champions that stack up to these mechanics.
In conclusion: When the focus for balance becomes making good champions bad, and not bad champions good- You will always and only have focus for the good champs, and always leave the champs in need neglected.
