Admittedly, I'm no builder stat-guru (a quick perusal of my threads will back that up!)
But, I was just thinking about how a Warlock is CHA based and a Favored Soul can be CHA based, and it got me wondering.
Obviously, you'd be playing more for the fun aspects of Heroics than building some end-game reaper nightmare.
But, aren't there a variety of both ranged 'pew-pew' aspects of both classes that could be brought to bear?
For that matter, I believe both have enhancement tree options which might have some cool 'aura' type abilities that might be built into something more melee oriented.
Or am I way off on all of this?
Curious!
