We got a normal ammunition and missiles and a Premium ammunition and missiles.
There is only one difference. Premium ammunition increases synergy gains by a certain %.
Each round (successful or failed), it gets automatically depleted and renewed, if enough Galactic Standards or GS are present on your account.
My suggestion is, that if you own a Premium license, you should get an exclusive and additional benefit.
All Premium Ammunition (weapon and missile ammunition slot) should be free of charge for the whole duration of the Premium license. Credits may replace GS.
Users without a Premium license can still get their ammunition normally, but for GS cost only and they need to do so for each new round.
Once again, Premium ammunition will still consume only credits then, instead of being free of charge!
I would like to remind you, that auto-refill option should not work with GS based Premium ammunition , since many people still get their GS deducted from their account, without their knowledge.
I would be grateful, if you can add an additional check option under game settings, so that we can choose, if we want it enabled or not. It should be disabled (unchecked) by default.
