I feel like we should just go with rito down this hole.
Just add unnecessary things onto champion kits. Not something that is extremely broken or OP, but under the right situations make it very very very strong.
Such as the Renekton changes.
I'll start.
Azir: When two soldiers hit the same target it is slowed for 35% for .5 seconds, and when 3 soldiers hit the same target it is slowed by 60% for 1 second.
Heimerdinger: When all three turrets are attcking the same target, they all get a 66% attack speed increase.
Malzahar: When malefic visions spreads it gains grievous wounds scaling 10% for each unit it has spread from, up to a cap of 100% ( :D )
Syndra: Targets hit by W are unable to dash/blink for .75 seconds.
Viktor: Upgrade 1 gives 2.5% ms, upgrade 2 gives 5% ms, upgrade 3 gives 7.5% ms + turns gravity field into a ground zone as well.
Zilean: Upon landing a double bomb on 3+ enemy champions. All skills on CD refresh not including ulti.
Not needed stuff, but would be hella fun to watch :D
