I never ended up really playing Gen 5 back in the day. I've come around, finally, to the end of BW, and it seems all that's left is to beat the E4 a second time and, uh, maybe the Battle Subway/catching legends. I'm probably just going to dump it here because the entire thing thus far has been a slog, and the rest of the game seems like it's just going to be grinding.

Could you guys detail me on the draw to B2W2? Improvements from BW, and what exactly I can do in its postgame that all make it so much better than BW (so I hear). I'm not going to bother if it's not really up to par with HGSSPt
