I agree with you. The lack of difficulty in the game makes it dull and the higher difficulty in the heroics makes it tough to find a group that knows what they're doing. And the group finder tool is obnoxious, especially as a DPSer (my main is a rogue, my alt a ret pally). But I've really been hankering to go back myself after cancelling in February this year. And archaeology is SO boring, with minimal rewards for it.
Star Trek is exactly as boring as it looks and I even gave it another try this February.
Star Wars is going to be fantastic. I think people are vastly underestimating Bioware's ability to make a fun, competitive game. I'm not claiming it's a WoW killer, but I bet it's competitive.
