Long term work on map production, for larger scale Frontline/Invasion maps.
Ehhhh... larger maps could be good, but they need to be properly optimised. Castello obviously has a reputation for causing frame drops, especially on 80 player servers. And also, if larger maps are made, please make it so that the entire map is usable. There's huge areas of Castello, Feitoria and Grad that you can't even enter and Crossroads has large areas that kind of fit with the cavalry-focus of the map, but don't really do much beyond serving as jousting arenas; there's no objectives there and so are mostly ignored save for the odd sneaky archer or carrot gatherer.
And please don;'t forget about lower pop servers,those of us on wi-fi find 80 layers to be too much to handle
We've taken this into consideration, we're still learning every day :)
