Yeah, the sheer number of enemy ranged can be a tad bit intimidating at first but luckily none of those chumps are anywhere near as dangerous as black goblin archers, fish men bubbles or a pissed off lich so you can actually fill ranged slots pretty aggressively as long as you're careful with your healer coverage. Awakened Vampire Hunters and Plat mages in particular hold up pretty well because of their high stats and MR respectively.
