Honestly it's a 'fool's hope' if you think X-Server will save ranked. It's comparable to server merges. It will only be a temporal effect that sweeps the bigger problem under the carpet. You cannot blame the players if the interest is not there, then try to generate interest. You're basically trying to do the work of the makers. Do you see people setting up arena q's on WoW?
I guess I'm a bit of a hopeless romantic; I think it comes with the territory, I am a Mets fan after all.
But what's the harm in getting some more people interested in ranked? It's a band-aid to a problem Bioware shouldn't have created in the first place and needs to fix, but I hardly see why making a community in an MMO is a bad thing.
