If I'm playing Karthus against Zed, is RoA or Zhonyas better to get first?
I've found myself in a Karthus v Zed match up twice now (I mostly play team builder, so no counterpicking options. Probably wouldn't pick Karthus at all if I knew the enemy was using Zed). The first one went okay, Q-bombed him so much he was afraid to engage, but the second one was aggravating as FUCKING HELL because even after Q-Bombing him down to about 1/4 health he was still able to dive me for a 100-0 then run the hell away before I could finish him, all while he's sitting in my Defile AND I'm dropping Qs on top of him.
I think I got Zhonyas third on that fist guy because he wasn't that much of a threat, but the second guy I started building RoA to get the charges rolling before realizing Zhonyas or even Armguard might have been a better idea for the first item.
Thoughts?
