Buff or Rework Karthus plz

he doesn't really counter anyone... is countered by 3/4 of the champion roster is countered easily by 2 items ( ) his w is useless, his q is easy to dodge, his e uses too much mana, and he can't just be "death dependent". you're allways out of mana, your w slow basically doesn't exist, too much counterplay... i played him a lot, i wish i could main him, but he's just too bad for the meta right now... i still don't know why he isn't part of the mage update!

he is a cool champ but... it's too weak right know... he needs to get to late game... but games end too soon for him to be good. just revert the w nerf, give him a little bit more mana regen, 10 ms and i'm good. thanks riot, i know you're gonna ignore me.
