Hmm.
x1 * 30 min. = 30k xp and 1.5 k gold
x2 * 30 min. = 60k xp and 3k gold
x3 * 30 min. = 90k xp and 4.5k gold
x4 * 30 min. = 120k xp and 6k gold
x5 * 30 min. = 150k xp and 7.5k gold
(with gen 1)
I would say x3 for both teams would be fair, but i could imagine another system.
1. Attacker will get a bonus Multi. if they capture 2 flags. The Defenders gain a Multi. if the Defend the first two flags in 30:00-23:00 (or something like that), when they defend the next two flags in the period 20:00-15:00 (and again not shure with the times idk how it would be balanced) and another Multi if they defend the last flag till the end of the round.
2.
Defender start with x3 and they lose one Multiplikator when they lose two flags.
Attacker start with x1 and they gain a Multiplikator when they capture two flags.
But with this system i would recommend to make the flags recaptureable.
Only some thoughts i hope it will just change from the current system...
