Coming from WoW and SWTOR it's the same over there. While WoW doesn't always telegraph where something is going to hit, after about 3-4 runs of doing the same raid or dungeon you'll either know exactly where to stand or be told exactly where to stand and it will never change. Bosses will always do the same thing over and over and how you deal with them will always be the same.
I do agree though, but I think that's just the nature of MMORPGs.
