I don't know anything about the game you're talking about. But I don't see why someone would be nuts for realizing that each person has their own preference for what they do better with.
I know alot of games, and people often feel this is over powered, or that is underpowered, etc etc. Alot of what makes each thing in a game overpowered or underpowered though has not only to do with the player, but what they are trying to accomplish or play against. Very very very many things in games have a rocks paper scissors type of relationship, and people might think rock is overpowered simply because they are facing off scissors most of the time. I play world of warcraft somewhat, and many people feel that melee dps classes are currently overpowered. But the fact is that they probably are about the same as they have always been, merely, the new dungeons people are running (new naxx and ulduar), are the most melee friendly dungeons in wow's history. Hardly any of the bosses have cleaves, whirlwinds, or novas that punish melee over ranged. No detrimental affects occur for meleeing the boss, etc.
Back in the day it seemed like every boss had some sort of ability or aura or whatever that would punish melee more than ranged, or punish them exclusively, now it seems like the opposite holds true. So currently, melee might be overpowered. But the fault lies equally with the dungeon design imo.
