Glad/whm for example... (one of many) My logic: I've only managed to get to 13 on my Glad so far and this combination is under the assumption that the Glad will get more AoE attacks (ie sweeping strike or w/e) to keep enimty and do minimal damage. If not..the class will likely desperately need this. Anyhow! My thoughts are that as a glad/whm you can run in and Aero a bunch to grab 5-6 mobs (or whatever 'pull' spell of choice) and use AoE attacks to burn them down as a group. All while self healing when needed. Rinse and repeat.
I've done similar builds in other MMO's, and while your single target damage is crap, you can fight large groups. Great for grinding and quest item collection.
Understand, I'm looking for unorthodox combos, that seems to be where I belong- in games that allow this type of customization.
What do you all think about the viability of the above?
What other theories can you offer?
