Ench/Dru, Ench/Sham, Sham/Mnk

[Treefall]

I'm trying to get a friend to level up with me over the summer, and I was wondering about the effectiveness of these combos.

I was thinking Ench/Dru would rock for dual charm and fear/snare, ports, etc.

I was thinking Ench/Sham would rock more later on, and especially in dungeons, with buffs and debuffs for rocking cash camps.

Then Sham/Mnk is the typical duo. I know it's amazing, but I can't think of how it would compete with Ench/Shm in terms of effectiveness...is it more effective? Or is it just a great duo to go if one person wants to rock melee?
