Generally the instances that people run from globallff tend to be the easier ones, because they tend to be idiot proof and so you get a good rewards:time ratio. There are a number of instances at the cap which will prove challenging for beginners right through to the experts. There are very few people who would claim that BfE T2C is easy, its certainly not something I think the majority of people could do off the bat.

In OD T2 Fear/Ivar/Gorthingy required will be difficult for in a less experienced/geared group. The Erebor cluster on T1 will require you to heal competently. For T2/T2C Fires of Smaug depends completely on people knowing what they need to do to not die. Flight/Battle will depend on the level of your group, they are certainly challenging for a group of casual players, with the challenges being in the realm of very good-excellent.
