It seems to me like one of the design choices made for RoS was to have the T1 visibles be much harder to come by, and needed to make the T2 visibles. After playing a fair amount in T1, I have gotten 16 RoS loot drops, but only 2 T1 gloves. I sense this is going to be a big task to farm T1 visibles before moving on to T2. EoK was not like this, it seemed like it made sense to skip most of the T1 visible stuff and just move to the T2 zones. I can see the benefit of motivating us to play some T1, but time will tell whether the grind seems too long in T1.
