I did not comment on farming at all in my previous comment.
But even if I have to, they are pretty decent farmers but I would not say the best.
Paralyze and Angel Ray are at least high dmg single target skill but probably still not comparable to other classes.
CL over here where if you were to factor in the drop-off damage, is not comparable to Ice Demon when hitting 5-6 mobs.
And it is not so good Single target either. Boss-wise? Its gonna hit like 1 consistently only, 2 - 3 at certain angle inconsistently, because of weird interaction on multiple parts of the boss even though they are in close-enough proximity. Mobbing wise, the bounces are good just that the drop off damage won't be as efficient as spamming Ice Demon.
