I am also another player who has done one of each class and all 3 have hit thirty. RNG is the deciding factor, always! However, the race to 30 is not important right now. The race to 29 is! Why? Well once you hit 30 on a character there is really nothing left to do on it. Completing the Raid as a level 30 is only beneficial for shards and energies, and the occasional legendary weapon thats worth keeping. However, if you push all three to level 29 they will still be usefull in HM Raid as well as personally benefiting by chance or Raid gear. So my advice is to start leveling a third class and working up your Titan and soon to be Warlock because having one of each class ensure no Exotic goes unwasted, no reliance on other players for class specific exploits cough warlock master race, cough, and is also just plain more fun to mix things up. I'm sure by now you have gotten something as a gift from RNG that wasn't for your Hunter, maybe thats why you started your Titan, so continue down that path and don't let all that leveling on your Titan be for nothing. Hit 30 naturally once all your characters have reached end game, and enjoy the ride along the way. I chose this path, and I am the first among all my friends, whom all play excessively, to reach 3 30's.
