>>48004199As a Gengar main climbing through Ultra, I can tell you that Hex/Sludge Bomb will not last as more experienced players know how to avoid Sludge Bomb and/or escape it as soon as you show up. Auto aim will completely fuck you over with Hex, such as in ambushes or as soon as another enemy/npc shows up on screen. Shadow Ball/Dream Eater takes practice to properly utilize, but it is still very good at ganking kills on enemies with 80% or less health, and also gives a tiny bit of health back. Also as an anon said before, Shadow Ball Haunter makes you actually useful for battle instead of being stuck with just Sludge Bomb until level 7 Hex. Shadow Ball has less cooldown than Hex, so you're not as royally fucked if you mess up somewhere, where as fucking up with Hex makes you a free kill.
