Rewards timer for war same as AQ
There must be a cool down timer for rewards of alliance war also same as AQ when a player switch an alliance.
Many players making dummy accounts to run 2 alliances at a time and they themselves losing in war in order to get rewards from each war.
E.g They made an alliance and take it to tier 1 or 2
When it reaches to top they recruit there dummy accounts there and switch themselves with high rated accounts to another alliance having rating at tier 4 or 5 and start winning their because they are too overpowered to win at that rating and this cycle continues to reap rewards by winning every war.
By doing this they getting rewards from each war.
I hope i elaborated what's going on. Hope some measures can be taken.
Its just a suggestion.
