T3.5 has gotten more and desirable gear and is done with pugs in <90 minutes every day. Same goes for T4 which is pugged regularly too albeit not as often as T3.5. Don't even get me started on cloud and Entity which is cleared even by the worst pugs several times every day. There really isn't a need for to be a 'raid-oriented' player to join those cause even the raidleaders don't show much gear/aa/exp usually.
If this is not fast or casual enough to form or join a raid for US players then their raiding time is beyond saving and giving even more gear or dungeon tokens is not going to help it.
