you can't really say they are good or they are bad, its called a "Class balancing" patch for a reason.. thats why , kinda hard.
Yea Nukers are good now my alt nuker is GL and he has 2 AoEs and the third one is around H level so u can literally AoE grind mobs like old days, and now most skills are instant cast with no global CD (more like the very old ck hyp) they do good against bosses now, I think they are in par now with warriors in terms of grind and maybe even better now in CCD.
