What are some types of Abilities you would like to see in future champions?

For a Support; I would like to see more abilities that are crowd control, but in a different way than what we have now, less stuns and things like the bard tunnel, but instead something that more rewards your team and their positioning, rather than punishing the enemies for being caught out, kind of like Kindred's Circle, but something like bonus attack speed, or cooldown reduction.

For a ADC; I would like to see skillshots that would ricochet off of walls, It just feels like that would be very rewarding and fun to land, also I would like more close range point'and'clicks that reward the ADC for taking the risk of being up close and personal.

For a Jungler; I would like to see more traps, be it like Shaco's boxes, or Teemo's Mushrooms, I feel as if the jungle roll plays well with harming the enemies before they get to the fight, as well as making it more risky to invade do to these traps.

For a Mid Laner; Nothing, mid lane needs to stay right in its current meta.

For a Top Laner; More sustain abilities, or passive armor and magic resist based off of missing hp, as top lane is more often than not, a holdout area, where towers just don't seem to fall as fast as they do in other lanes.

what do yall think/would like to see? :o
