passives should supplement kits not replace/dominate them.

so in order to explain the title lets look at a couple of offenders to this rule champs who basically have their kit revolve around their passive. without their passive these champions could not function period, their passives are: overloaded un-interactive its what will always make them toxic/unfun to play against.

are examples of someone who has a kit dominated by his passive. flat out removing it would cause serious repercussions. and their winrates would drop significantly. the amount of buffs they would require to their kit and base stats to function properly in the current game would be huge.

here are champion who have IMO well designed passives. they are interactive: meaning that BOTH players get rewarded if they play around this passive properly. removing it would cause a drop in winrate but some rebalance in other parts of the kit would make up for this loss. (ofc gnar would have to be reworked but for the sake of design i would say his passive does the job) Orianna is already a old champ and she has withstood the test of time admirably.

what im trying to say riot is that any champion who has their ENTIRE kit revolve around their passive historically speaking will always be a contender for toxic playstyle's or the nerfhammer.

just my two cents.
