If they let RW die completely, then we'd be missing all sorts of stuff. Rival Wings in general is a core part of the PvP Experience now(considering it's far better than the trash that's FL, let's be honest here) due to it just being 24v24 instead of the 24v24v24 setup.

They should put a focus on it for Roulette because not only is one of the rarest, coolest titles in there(even at 1,000 wins), you also have both the objective-based gameplay of CC and the large-scale fighting of FL in there. It's the best of both worlds!
