I will list you several game modes which could be good in AoS.
-Capture the flag (Steal ur enemies flag. and take it to ur base)
-Search and Destroy (Bomb/defuse)
-Assault (1 Team defend their base, the other team tries to attack and destroy it. Objectives has to be done to complete their mission.)
-Hide and seek (1 team on 3-5 players get forced black screen 30 sec in the starting of the round. The other team hides in small caves etc. (Custom made maps for HideNseek have to be used))
-FFA (free for all, ALL vs ALL, no teams. Everyone versus everyone)

Other tips:
-More weapons (Sniper class <--- 1Shot boltaction sniper. 1shot in head, 2 bullets other places. Heavy class <-- 100 ammo with medium hit demage. High recoil
-Able to drop and take ur enemies/teammates weapons.
-Fix server lags... My ping shows to be 10 etc on the server list. But 200-300 ms ingame.. bad lags always..
-Able to start the game from my computer. And get server list ingame. Also make it able to Host local server. Etc.etc.
