This is everywhere in rp. But it isn't exactly a bad thing, and if it was, you can't really avoid it. We do what we enjoy doing and usually we then also get good at it, and most people come up with some kind of ic background for this ooc skill. Like Daren designed armour and uniforms and had experience in architecture and building. These both were my ooc skills,building in mc and making skins for others, and I used this to get ic money.
It would be stupid to have your character specialize on something you know nothing of or cant do as a player. Don't be an IC builder if you suck at it oocly.
