Personally, I think they're way too easy. I've done up to Athiss and there's been almost no challenge. I've been under leveled or leveled appropriately each time for the desired flashpoint.
The most disappointing thing for me, is that the trash is so un-engaging. 90% of pulls require no coordination, focus or CC. I know trash is trash, but I was expecting it to require some coordination beside "Tank - AoE aggro everything, Healer - heal the tank, DPS - do what you want".
Is it just me or do you guy guys find it too easy as well?
I mean, I've only experienced the first three flashpoints, so if you've played past them, share your opinions on the later flashpoints, too.
...because you needed CC and pull coordination in the Wailing Caverns...riiiiight
