Although my main's been a hunter for 3 years now, I've recently started to play a rogue as my main alt (doing fun raids on weekends). I've tried all 3 specs in PvE (I'm not a PvP'er, srry) and I must say Blizzard quite succeeded in letting all 3 specs have their own 'feel'. Although Subtlety is supposedly the least viable spec in PvE atm, I still prefer it over Combat/Assass, just because of the playstyle and do above average dps with it. So rogue boring? Depends entirely on the player imo.
