Ment or Ench?

Either will work fine, although the Ench will have an easier time early, the Menty starts to shine when he gets to 20+.

I like the Menty because of the ability to charm a mob in the middle of a pack and when everything jumps on it you cast an AoE DoT and just kite them which makes for a relaxed and easier leveling, just be prepared for a lot of running.

Ench would have the advantage that groups want 2-4 bombers in their group for leveling and farming so you would always have that as an option, while these same groups will want 1 menty at most and sometimes they skip if people have the right RA's and a bard.
