so you sure that karthus in arurf is ok?
yes or no
yes or no
How does that happen? Do you have a replay? I know his Q got cast-buffering a while back, but I hadn't heard of it making him actually good in URF.
In this one, three people were low health. That's Karthus time. And then Amumu comes in, tries to use his ult to interrupt a channel when all it does is root and disarm, and doesn't use his Q to interrupt the channel (the initial hit stuns, and the CD starts at 3.2sec in URF and goes down to 1.6sec at rank 5), then stands there trying to outduel Karthus Q spam, which, even outside of URF, is an unwise decision.
Ah, they all grouped up, walked into his wall, and stood there while he spammed Q. Yeah, gonna have a bad time. Even outside of URF, that's an unwise decision.
op ult :D
presses r, enemy team realizes they haven't gotten their zhonyas yet, and those who have already used it.
If you have 1 or 2 other big threats karthus either will kill you or force your hourglass(you have you pay ur karthus tax) and they catch you out. I've won 3 karthus matches and lost 1 due to the enemy having mao, and gnar.
