I've recently rerolled and started an MP. MY lvl 60 NT is still using the same nuke now as he did 20 lvls ago and frankly Im getting bored of beeing unable to solo anything other than greens.
I normally do mission so I can run when 2 greens or one yellow attacks me. My ac is 1400+ and I got 1200 hp and 1250 Nano. Thanks to resists, fumbles, 80% of all hits doing minimun damage and interuptions I normally have 10-20% of my nanopool left after fighting a green mob.
I decided to give the MP profession a try and belive me I just got a new game! MP gets new pets very often so you always got something that pushes you to the next lvl. Got my MP of to 17 today and I can say I miss my 60 NT at all!!
Do yourself a favor! Reroll as a MP! The heal pet rules!
