Considering the large number of players that GV and the recent changes in the GV system (not withstanding all the new GV models); it would make sense to make the maps more GV friendly. Just add in more spawns and voila, done. They did after all, change the strat system on every single map.
p.s. I'm not a Gver, but can see that they promote fights - ground and air. The more places they have to spawn in, the better the chance to spread the horde. Even if only a little bit.
