NA has so many tier1 capable duelists that 2 of them (Reduxx & N4rrate) are having to waste away in other roles in order to keep a spot
honestly I think it's a good thing overall (obviously bad if you look at it from the individual players standpoint)
it means that the standard of duelist is very high (as only the best will stay on the role)
also it means that the excess who don't cut it can play support agents, on which they'll still have really good mechanics, meaning you have much better firepower
