Tier based ranking would definitely be nice. Especially since you could easily see if some high tier player is the one wrecking everyone. Instead of "no freaking way", you'd hear more "what is he even doing here?!?". But seriously, you'd know if you're playing a skilled player or some low ranked goof ball who may be manipulating his connection. And let us not forget, if it's tiered then Bungie can just focus on connection based matching in your tier. Look at that, skill gets to be a factor and connection is still the basis for your match making. I solved the PvP problem! With your help OP. :)
