Yea, the damage is absolutely stupid.
I think Subzero shield should only about freezing enemies, not reflecting damage.
IF they want to have a highdamage-reflect skill they should add a new skill to a high rank class and give it a short duration and longer cooldown (like, 100% reflect, 15~25 sec duration and 1~2 minutes cooldown).
reflect shield need scale with int
i thought the reflect scaling is spr based? was in tosbaseās info wrong? 
i personally think wizards need more skills that scale with spr. it would make more sense if cc needed spirit to work properly.
that and a rank bonus for non str/int statsā¦thatās just a slap in the face to everyone who wants to be different.
I think this would have been diffirent if you take the warlock path rather than the RCā¦
