Some realy bold ballance ideas
The main aim is to influence champions playstyle in a way that would make them more ballanceable across all elos
So first thing is about riven . Riven is always known for being a bastard who goes full ad and can tank twice as much as any tank while dealing twice the damage any carry can deal. That was a hyperbole of course but riven is ... intense, she can do much in all areas rather fast and efficient. So the thing that i consider a good gameplay change for her is a) give her a resource ... but not mana nor energy ... resource that wouldnt limit her capability to be intense like she is ... but would gate her on the amount of time she can unleash that power in short time, thats why i simply think she should get either an overheat passive like rumble (no auto atack damage amp during silence thou) or a simple resource that replenishes with time and she expends it while casting b)reduce her cooldowns
This will influence riven in many ways -she will have downtimes that she lacks (what her enemies want) -while still having her infinite spam intact (what riven players want)
Its a new power for her and new counterplay for her enemies. Also being a good riven wont be all about animation canceling anmore but about managing your resource so you wont run out of abilities mid fight ... so riven might feel actualy more powerfull but enemies wont feel like they are left with 0 options to counter her.
Which creates a giant floor for her ballance and player's skill to shine.
Next thing is katarina ... and imo this one is the boldest idea one could ever have (thou its not mine). Make it so katarina cant have her ult interrupted and simply ballance her numbers accordingly.
Katarinas gameplay would shift from decimating teams in seconds (if she is lucky to not get cc'd) to unleashing loads of aoe damage in teamfights and being a cleanup mage.
The thing about this is that it could make her viable at lcs while making her leave the throne of solo q dominator. Since lcs players wouldnt simply allow her to use her power ... while yolo que isnt coordinated enough to stop her propertly. Also ballance wise it opens up space for the rest of her kit to become usefull and more tied to her gameplay . Again its a thing that does not kill the kata fantasy ... while also giving something for her enemies.
Give me all your downvotes
