Fix the debuff root problem. Properly this time.
Make NT (and nt only) nukes do more than 40% max HP damage. (if they do more damage ala Izzy's little nuke, last word, Kels)
Increase the resist rates on ALL debuffs to crazy high rates so those with high NR will be able to resist them.
LOWER Nano resist of mobs so people can still debuff them in pvm play (although imho if you have trouble or are supposed ot have trouble with a yellow NT player's resist, you should also have same difficulty with yellow NT mob)
Increase the effectiveness of the Crunchcom line, if need be make a few other ones (~40-50%) self only or NT only.
