I was in a similar position. I played Blue, then got back into the game with 4th gen with the introduction of online battles.
Initially, I found the adaptation from casual to competitive play overhwelming when bringing my in-game favorites to a few online matches. I found that if I wanted to...
I think we're better off with regions based on smaller areas. This would allow more regions to exist.
I would worry if they made a region as big as half a continent or so, it would make me think the end would be near :-(
The stag legendary (assuming X?) does resemble the musketeer legendaries from BW.

I enjoy puzzle legendaries far more than roaming ones. Roaming pokemon can easily be found by a lv39 pokemon and a repel. Puzzles can be challenging and are more rewarding.
In BW I found myself short in the Fly user department, but picked plume fossil and was so impressed with my in-game archeops that I bred a competitive one.
