Reason why I said Vit will be more appealing to warriors come 2.1 is because of Inner Beast changes. However, there are some might debate that we now turn to Storm Path for our healing needs, which in best case scenario is only performed once every 10 seconds, only heals about 140HP now with Gryphonskins, Probably 145 HP when Allagan Axe gets bumped to ilvl 95. It is still way far from being able to replace the 200% Inner Beast which should be around 600 HP heal lost, which can be performed every 20 seconds.

That would give it a 310HP heal difference, if you want to look at it deeper we might have to drop Storm Eye all together, if you dont you can expect Storm Path every 20 seconds, which would make the variance be 460HP. This is the reason why I expect STR purely in the for of stat allocation will be more detrimental postpatch. With that said, still I believe Gryphonskin has a place in current content as BiS gear until new harder hitting content is released where that 400 HP will make a difference between surviving and feasting on dirt. You should expect to have around close to 430 STR without STR allocation in Party with Gryphonskins and other equips being ilvl 90.
