I've 100% fixed the cass situation for all pre-rework cass players
Just play
, he's way way closer to the pre-rework cass than any cass changes you're gonna see.
Seriously: I used to only play two champs mid, ori and cass. Now I play only ori and malz. The switch was easy and he feels very similar. Aoe dot (functions like one with ult), a single target dot, CC on demand, wave clear. And unlike the new cass he's actually a dot based champion.
