When I got a ISSB for my warrior, I was happy to get a nice helm, lately I got the Kael piece... and was unimpressed. Tier 30-55 (closer to 55 though) vs. Kael drop... should be an easy upgrade...
Now, not only my warrior, but my cleric and bard also get barely any improvement going from ISSB to their Kael set helm. I'm not saying set should be better than anything else available, but Tier 30-55 and Kael (70+ group) should definately not be on the same level, right?
