Hi!
Just stumble accross your post, and seems no one already answer this. Anyway, since the host is patched or they changing the Server Name, i recommend to use port blocking. Try to block 443 and 80 port while in game and remove the blocker after the match is finish. You can do this using No Root Firewall or using IPTables (Requires root)
[For Advanced User]: You can start by disabling unnecessary files using permission 0 and disable the game services using MyAndroidTools Pro. As for memory manipulation, you can try to nullified the game memory maps inside proc using bind.
>mount -o bind /proc/2/maps /proc/[Game PID]/maps
>mount --bind /proc/2/maps /proc/[Game PID]/maps
-Good Luck!
