I want a sort of battlemage... Might not be suited for a hero class, but I still want it!
Imagine it like a more successful Enhancement Shaman, that uses offensive magic and melee combined.
Could have one specc that focuses more on magic, one more on melee and one that focuses on defense (PvP, or maybe friendly buffs to cast on players?).
Sadly most of the spells/abilities that I can think of that would be suitable already excists in-game
