My understanding is that the points will not count. This is specifically put in place to deter people from getting bot accounts to join and alliance, dump their units, and then leave. This was a huge issue in the past. Putting the 14 day delay in makes this impossible.
...I don’t see why players who enter an alliance, contribute towards points immediately, and stay with said alliance through the gifting event can’t have their points counted immediately. They should only have to wait on the timer to claim rewards, not contribute points.
Because then some alliances could still exploit the bringing in of hundreds of sub accounts just to dump in points right away and then rotate out for other sub accounts.This way it limits it to only 30 maximum potential accounts even being able to contribute points.(An alternate idea many have suggested in past is if they were to allow points right away, but then DEDUCT their points back out of Ally Total whenever someone leaves the alliance during the event. But that would also necessitate not allowing anyone to claim any of the Milestones along the way until the very end, which would not be good).
