After the rescaling of the lower level mobs, a lot of the newer players to Dornogal are players who might had just returned and thus have no appropiate ilvl gears from the pre patch event.
So I suggest for Blizz to create an Adventuring Gear Vendor NPC for characters between the level 68-71 to ease this issue. As a matter of fact, create Adventuring Gear Vendors for each level milestones where there is a sharp increase of ilvl and enemy diffuilties between the levels such as from level 60 to 61.
I do think the ilevel of the intro gear should have been bumped a bit, regardless of the mob change. Even if you were coming in from greens in DF, 408 just felt low and was 100+ ilevels lower than the top end gear in DF. I don’t remember for certain, but that felt like a larger disparity than in some other recent expansions.
