I have alt that is Wd/S/D level ~30/30/35.
That alt is capable to survive being left alone in not so friendly environment with mobs 5 or more levels higher with ntBuff enabled when on Wd/D. I don't have it even properly geared, but I did opt also for mage gear/stats.
That alt is my ore processing/collecting alt and will have to wait until leveled. (have 2 other alts that I urgently need to level

)
