Well i was think more or less on active servers instead of idle like DR or JB but maybe have an auto kick for people that idle on them making it to where they have to play the game too get points, Also you are right about the title but they just take a while.
Please make the random drop of credits a smaller amount of time rather that something like twenty minutes. The contracts help with this but i would think it would be better for players that have played a lot on flux as they would get rewarded quite a bit allowing them to use the shop.
