If server is small - it's invisible, but when the community grows it becomes a threat to NC. They will try to kill all top servers, so if this would happen you could:
a)go to a medium/low populated server
b)create server from some place where NC has no power
c)hack NCsoft
:D
Yeah, kamaels aren't easy characters with 2-3 skills like etc. sagittarius. You hit-stun-hit-skill and so on. Kamael have more skills and tacktical things.. but all in all they quite suck becouse of their dmg unless you get buffs n start killing people by fast shooting speed with many crits :D
