well everything isnt perfectly balanced, thats just how it was back then. If anything it can help to push up ulduars ilvl a bit to make the gap less, people are gonna want to go back to ulduar nontheless, mainly due leggy mace but also other items. Ilvl doesnt always trumph as we can see in both classic and TBC. heck me as hunter was still using DST going into SWP, i still cleared BT each week to get my hands on the illidari council trinket for example. I feel blizzard is making a hen out of a feather. Ofcourse i understand they want the tier last longer and thats fine, i just think its wrong that ToC and ICC especielly is going to have to suffer just beacuse of one raid tier.
or they could squish the ilvl in ToC and leave ICC alone, thus making it a bit more challening in the start of ICC and scaling classes wont be punished in ICC thanks to ulduar.
