In other news, I just learned a friend of mine is joining us for a session. He'll be a gestalt as well, thus making it 5 PCs, and only one non-gestalt PC (me.) Barbarian/Scout. Overall I'm less worried about this since ranged sniping is something we could use more of.
Enamal,
Eh it wouldn't be that much different in my view than combining a monk with say a ranger or a rogue. In my mind, it's viable but probably NOT as good as other combos that work better for scout (IE barbarian, ranger, warmage) or for monk (cleric and paladin.)
