Yeah, I could see that being a problem, when you get to be like level 5 and your fighter is tanking through crap, but can't do extended crowd control, where you would need a mage, but he's only level 3 and can therefor only cast a couple of worthwhile spells before needing a rest or something (I forget if they work off a cool-down or if there's a carry-over from 2nd edition where you have to rest to get stuff back). So like 3 shots of magic missles and he's done for an entire floor, or you keep resting every 2 steps after every encounter. But I remember having to do similar things in Baldur's Gate during the early levels. Early levels in D&D always seem to really suck. Fortunately in Icewind Dale, you level up really fast, or at least it sure seemed that way to me
