I was a jack-of-all-trades too in Forum Brawl #1 but in the end I tended to be the one who was filling the holes of missing submissions. Because of this, I think you should be proud of being a jack-of-all-trades, since it is MUCH easier to replace/aid a fellow member as such rather than being master-of-one & jack-of-none!
In this competition, Jack-of-all-trades are like rainbow decks; totally OP when the conditions allow it.
