The thing is that you can't show more of the map, if there is no more of the map. Example being a lot of older maps like the El Nath woods backgrounds suddenly not lining up properly and with the sliding foreground effects (clouds, water, fog) getting cut in the middle since they no longer cover the entire map. Stuff like that would take ages to change.
zooming in and changing the actual resolution are not the same thign
in fact its the exact oposite
right now if you want to play in full screen youl be stuck with a game that looks like some one zoomed in heavily and its very pixelated and grainy, not to mention the text ingame becomes blurry
what were asking for is if there will be an actual 1080p resolution in the future
instead of zooming in the game it would actualy show MORE of the map your on
hell you can actualy make more UI space with that resolution to include more skill buttons
