At least right now, my Melee people are on par with my ranger and caster. They do a lot of damage when they get near someone.
So they do the same damage as a caster... except they have to spend AP to get in range, have 1/4 the utility, are susceptible to mob effects (like explosions on death, or poison on hit, etc), ground effects, and can't reposition as easily?
That really just proves my point. Take the fight that takes place in the hideout, early on in the game around level 6. If your melee rush in there, they get hammered by 6 mobs at once, can't avoid the dog death explosions, and can't escape (without Ranger/Scoundrel). I just did this fight 4 times with all 4 of my characters attacking, and every time the melee did next to nothing. I leave them back, effectively doing nothing the entire fight, and my Wizard/Ranger duo everything in 4 turns. This shouldn't be the case.
