I think it's a matter of oversight. I hope it will be corrected.
<img src="/ubbthreads/images/graemlins/div.gif" alt="" /> had a SCAD of broken skills as well - either they were complete crap (Ranger's sight did twice the effect of Warrior's sight), broke the game (Aura of Command), or made the game incredibly easy based on errors in the skill (abandoned Reanimated monsters became alive and hostile once you teleported away from them, allowing you to treadmill; reflect missiles bounced EVERYTHING off of you and back at your foes, carrying with them poison charges on your weapon).
As far as I'm aware, these were never fixed.
<img src="/ubbthreads/images/graemlins/beyond.gif" alt="" /> doesn't have broken skills that I can tell... but it has a lot of garbage ones. The mana cost on spells is ludicrous for its effect; a spell used to cost like 8 in DD and do incredible damage. And if you're not a mage, you have no fun combat skills whatsoever, making you a passive tank. Not my idea of fun play.
