Melee professions are supposed to get in melee range. If there is one thing that makes absolutely no sense, it is being able to completely ignore another player as you kill them.
CC tools are supposed to be temporary tools to shift a fight in favor of the CC using profession slightly. Any point at which a CC tool can dominate professions is a point where CC tools are broken. In that same sense, any time a profession relying on CC tools cannot make use of those tools, they are also broken.
Rage spamming is bad.
Static CC tool immunity, or near immunity is bad.
Chain rooting is bad.
The only thing I haven't seen addressed is %resistance against CC tools. As long as CC tools work, but melee professions can also reach any ranged profession, it should be fine. More melee CC tools would be appropriate in that regard
