so taking exhaust top is becoming more and more popular
this doesnt at all prove that a certain summoner spell needs to be given counterplay.
not at all.
2-3 exhausts a game if the mid takes it as well pretty much invalidating your damage .
lets nerf those numbers now shall we? getting my armor and mr reduced from a summoner spell like exhaust sort of makes no sense xD
increase the cd or lower its duration or let qss remove it.
anything.
its an "anti interaction" summoner spell.

because
etc champions because they are somewhat squishy but good dmg.
where the don't really get in fights often in lane, they get poked and walk back and wait till the minions are near their tower or under to cs. If they get a gank which is 90% most junglers first stops of ganks because top players push more often than other role champions the exhaust players will be overextended and flash and most likely exhaust aswell to escape a potential death from the enemy top lane and jungler.
Better than flash for him
doesn't need it and it either replaces flash or he loses teleport
