Sounds incredibly fun, but I doubt they'd do it. If they're going to slowly rebuild/heal things that got destroyed in Cataclysm they'd need to phase everything. Wouldn't make sense if you're rerolling and everything is perfect again!
Tbh guys, I'd take the redridge workers over the westfall ones any day. Fixing 1 house has got to be easier than a bridge. Not to mention those poor sods got their precious buildings on fire for an expansion.
