I agree with the need for more detailed raids, the way that coil currently is it doesn't give that epic feeling that more open and detailed raids do, doesn't even need to be longer, just be put together into one big dungeon instead of teleporting into different parts between each turn, hopefully they'll do this in the expansion for Alexander. As for more difficult thrash mobs, it will be fun in the beginning but after a while it will just be a tedious task unless the thrash mobs gives some kind of reward, needing a lot of focus for a zero gain will just bore people out after they cleared the thrash once and will result in trying to come up with things to avoid killing them like it's done in T10 and those mobs aren't even hard.
