20/20 Hindsight on Game Balance
A lot of the reason certain champions have become really good or dare I say, "overpowered," is because of how Riot has changed the game with the addition of turret plating. WIth a stronger emphasis on doing well in the early game, we see, especially in top lane, more champions being picked that have a good early game lane advantage. That is, turret plating combined with the nerf on teleport cooldown. That's also why we see people taking biscuits from inspiration in most roles as well as corrupting potion in solo lanes.
Riot is now nerfing some of these champions with very strong early games as well as nerfing corrupting potion. But I think the question that really needs to be asked here is, does Riot intend on keeping turret plating and the teleport cooldown nerf for seasons to come? Will they undo all of the damage they've done to the assortment of champions made strong in this meta once they take the meta away?
Just food for thought. Would hate to see 20 champions become garbage and need reworks because we decided to try a new meta for only a year.
