Thats just rude. He isn't that strong relative to some of the other characters in FT, but he is not terribly weak. He could very well hold his own agents the mages of some of the other guilds.

And the reason he isn't a main character has nothing to do with his magical power. He could very well be a main character if the author wanted him to be, he would just have to develop his backstory. Happy is fine as a main character, and he most definitely has a lack of magical power. He just fits well with the story.
