I'd recommend against human only while leveling. The damage from bright nova is just too good. As Microcosm mentioned dwarf is where its at for most of your protection while leveling, since you don't need breakfrees. You can simply shift into dwarf when held, immobd, etc... and also you get a monster heal when in dwarf form. At 50 even with perma light form, dwarf still gives an extra heal, and an extra aoe. Personally I'd take some time to read up on keybinds before playing a PB or WS. They will make your playtime so much easier, and definitely a lot more fun. That's part of the reason I avoided the AT when I played on live, and had no idea what I was missing out on.
