I play ACI since april with my buddy. Most of the times every 4th or 5th mission was a Raid, but for a while there is absolutely nothing. We play 4-6 games every afternoon but we didn't meet any Raids in september. Almost three weeks!Are they "upgraded" the Raid frequency or we just very very unlucky? :(
