How does the power gap between GS1 and GS500 translate into a singular level 30? Going from GS1 to GS500 is a bigger jump from simply going one level to another, so I'd imagine Level 30 would be a spike in power or it would just be compacted/nerfed? Also, since non-WNY players can progress their GS to 515, how does the extra 15 GS translate when they finally enter WNY?
I don't quite understand the first part of your questions, maybe you can elaborate a bit more?
In terms of Gear Score going to New York: Level 31 items will be stronger than Gear Score 515 items.
