I played as an nonlifer(about 6 hours / day) with my magician and ... Reached lv 50 in about 23h51m
6h/d is a hell lot of time playing. Almost a full time job. IF I stopped going to the gym, I could reach 8h/d but doesn't worth. So far, leveling to lv 50 was 2.5x quicker as an magician than as an necromancer. I"m not saying that necromancer is weaker, quite the contrary, in long fights or in battlefield control, nec > mag. As for deaths, I only died once. At lv 46(any command which shows deaths, so I can prove that?) I din't saw the DoT in my char and mismanaged my hp in this death. I also got close to die other times but luckly GATE spell saved my life.
So far, I really loved MAG. A powerful magician with powerful servants is what magicians are.
The unique thing that I din't liked much about magicians is that their offensive spells are too "pyromantic", would be better if a magician would have to attune to a element and had spells based in the element which they attuned. Also din't liked that I have only elementals and summoned mobs. I wanna own a golem!!!
