one point im interested in is if there will be somethen maps which are bigger but with more "dead space", so that not everyone has only a 5-10 seconds way to go the help on another line?
thats one point i noticed why its hard to overrun a enemy. if you kill the enemy demigod, the time he needs to come back into battle if he walks is not realy long...
and maybe a combination of war idols and flags would not be bad... something like this:
if you can hold all the flags at the same time the speed the war idol is improving is higher, this also got several levels of bonus-speed.
for example if you are holding all the flags:
time | rate of speed increase
0-2 min | 10%
2-5 min | 20%
5-10 min | 30%
