Hey, I've been getting P2 H Sha the past couple weeks, and it seems my Rolling Thunder isn't giving me appropriate mana regen. Lightning shield is up (triple checked), I don't start my CL spamming until 3(1), while keeping a flameshock up on Sha and an add. Once 4(1) rolls around, I'm OOM. This happened a couple times on H Will as well when we were AoE killing 2 waves of rages. Any input? Seeing similar problem? Any help would be appreciated!
My toon is Melioidosis on Mannoroth US
