Vampire, Pillarman, Kars, and Wamuu are extremely weak compared to their manga counterparts. As everyone with working eyes can see, almost nobody uses Specs, because most stands are stronger. Vampire's only benefit is lifesteal, and it doesn't do that extremely well either. Its regeneration should be on par with high spec Hamon, if not far better. Same with Pillersquad, but far better than that, and take 50% less damage from those without active hamon. Vamps should have 2x stronger punches than standless people, and 2.5x for Pillersquad. I could really go on about Kars, but I'm trying to keep this brief. Toggleable Light mode with current y being the left click, and doing more damage when being in direct contact(like MiH) Wamuu is alright, but it needs the strength bonus+super regen+durability. Pillarman should get the same as these 2, and kars and Wamuu should have C+# abilities that allow them to use base pillarman moves and enhanced versions of their current moves, similar to Joseph Hamon (Joseph Hamon currently is far far stronger than all of these Specs).
