Both Karthus and Cassiopeia have been officially disabled, thanks to the AoE bug I mentioned earlier today. As I said in that post, those two champions in particular seem to benefit in big ways from the problem, though Riot wasn’t clear on how widespread the issue actually is.

Here’s the official post:

Due to a current bug affecting AOE damage spells, we are temporarily disabling Karthus and Cassiopeia. These champions are disproportionately affected by this issue and will be re-enabled when we release a hotfix. Rest assured that we have a dedicated team working to resolve the issue as quickly as possible.

This is one of few times that we’ve seen champions disabled thanks to bugs associated with their skills. I’m glad to see it, though. I was getting sick of Karthus hitting me from crazy range.

If you’ve been on the forums lately, you’ve no doubt noticed the threads bemoaning an AoE bug. The bug, as far as I can tell, allows AoE spells to land at a larger radius than their animation. Among the top offenders are Mordekaiser’s Siphon of Destruction, Brand’s Pillar of Flame and Caitlyn’s Yordle Snap Trap. Riot has yet to respond, or at least yet to respond in a post that I can find, so it’s unclear whether the bug is official or not. I will say this – I seem to be getting snagged by farm more traps than I used to.

In my mind, this is a really tough bug to assess. It’s frustrating to get hit by more spells than I’m used to, but I can’t help but think that my paranoia about the bug feeds into my analysis of the bug. Still, I did have a Cassiopeia land seemingly every cast on me, even though I had boots at level one. It’s not totally inconceivable that she was just the best Cassiopeia player I have ever seen, but I’d bet it’s more likely that there is some sort of bug.

Have you noticed the AoE bug? Seen a prevalence of AoE casters like Karthus and Cassiopeia?
