Mod edit: See post #4 below for information
It would SEEM to me that a city's GC rewards should benefit the classes whose Guilds are within their borders the most. However, I recall a very detailed thread for DRG optimization back in 1.0 that had suggested Maelstrom, citing their weapon/gear as best for DRG optimization.
Just curious if anyone knows the deal yet for 2.0 - where to go to best optimize your specific class and all that. Figured I'd ask!
