I'm concerned that all the 3-piece sets are helm, cloak, and armor. As a dps caster, this is particularly problematic, as I feel as if I'm being told I need a perfect Gem of Many Facets to get to use one of the new sets without it being a major step back power-wise (keeping in mind I already have to give up legendary dragonscale) when I look at the new gear.
Maybe if there were a few additional dinosaur bone items (goggles for example, as I don't believe there are any in the whole expansion that we've seen so far), it'd feel a lot less restrictive when taking previous gearing into account.
Edit: Example on my sorc, I have to replace the Legendary Magewright and Legendary Elder sets to use one of the new 3-piece sets. My only option here not to lose something from +6% crit chance, +15% crit damage, +3 spell DC, and +3 spellcasting stat is to grind for a legendary gem of many facets with elder's set on it, when initial impression seeing the spellcasting robe or light armor is I could wear 2 3-piece sets from Isle of Dread to replace these set bonuses. Unfortunately, both Isle of Dread sets would require the exact same items, so at best I spend an unknown number of threads to not lose that power while still losing legendary redscale anyways. It's hard to not feel like I'd be better off not using any of the new 3-piece sets as a dps caster as a result.
