@Drifter : Ya, everyone from this world is applying their own logic, which is flawed and seems to be single stat build only. Not one person asked what his healing stat is at. Plus even if his current build sucks, they could potentially get him to adjust to a "competent" build with level up bonuses over time, but that would require asking stats to see how far he is off. If anyone actually asked and/or saw his stats they would take him in a heart beat, as he only really needs at most 3 stats and 2 are already well beyond the level needed.
Really what some party should do is ask him to prove his worth, and test his abilities. But since the stat is fodder to them they are not bothering.
Though it feels like evasion is undervalued, since you would need to invest a lot before you start really seeing the benefits, but the rest you see them immediately. But he is seeing the top tier benefits immediately. Which is why this series kind of feels like it is about the hidden builds in many RPG's where you often see non-standard options combine to form something broken, or something go from useless to god tier as the ability levels and grows. So a "useless" level 1 build slowly becomes way to OP by the time you level up.
@firosahoge : and by the time he runs into a real AOE user we will have had time to build up his other stats and gear to survive. likely his stats are not that far behind other level 1s, so AoE's that would not wipe a level 1 party should still be survivable, and as long as he does not go down he will heal and keep going. after proper leveling and gear the difference will be even less. Also there are games where evision can even let you avoid AoE (rogue's in D&D are a prime example), so do not try and call him a non-gamer. It depends on what types of games he plays, as they are to varied. Really the whole AoE argument is just trying to sound smart because every build has to have a weakness and you know how you best survive an AoE effect, by getting the f*@# out of the area, which master level evasion would really help with. Plus unless strong AoE's are extremely common and unavoidable he can easily juist not go to areas when he will face them, and stay back in fights against monsters that use them and avoid almost every instance of an AoE effect.
