Now the key phrase in that article is "if time allows", but what exactly kept them from even making minor tweaks throughout the course of an entire season? The spawn trapping is as bad as before on a map like Dead Cliffs.
Edit: Thanks for the silver kind guardians!
Also, I wanted to clarify spawns versus spawn trapping. We all know spawns, ie where you pop up, is bad on any map. What I was referring to here with these maps is spawn trapping in control, ie trapping people on A at lockers on Dead Cliffs, trapping people at B on Legions Gulch, etc. Absolutely nothing was changed via cap points or heavy ammo spawn while these maps were absent.
