Hi,
seems you have lowered the drop rate of teleports on rebels. I have received only one teleport in three days, approximately same drop rates through the alliance. Even if you lowered to push the buying of commander stamina, on this drop rate it doesn't make sense. I understand, you want to make money with this game pushing in game goodies, but watch out not to be too greedy and end up as a mere pay to win game.
