So there's the mana readouts and this appears to be erebus' weak spot in terms of base stats, his max mana is pretty low for the first 4 levels and his mps is pretty attrocious too. This should end up meaning that an increase in mana cost for his abilities is going to hit him pretty hard in terms of what he can do.
Doing DPS from base stats is going to be a bit more tricky as there's an upper bound a lower bound and an attacks per second, so I'm thinking either just average it out, or what I'd prefer to do, is make a graph with coloured shaded semitransparent regions.
Yaay data analysis is FUN!
