CTF Suggestion (Coins)

The problem I have with this is that with the current credit system, a player gets 2 credits per kill. So with your idea, every 10 kills would equal 4 credits, which would actually be less than getting 10 kills under the current system (10 kills would give you 20 credits). Earning more credits should be focused around objective gameplay, which it technically already is. Capturing the flag earns 50 credits, recovering will earn 10, and carrier kills earn you 20.

However, if you meant for this idea to be added on top of the current system, i.e. getting a 10 kill streak would give a player an additional 4 credits on top of the credits that they already earned, then it's not a bad idea. In that regard it could actually be a pretty decent way for players to earn more credits. Just a warning though, once players get all the classes, the whole thing becomes pointless. The price of classes is 1/2 of what it originally was, and adding new ways to earn credits might make it easier than it already is to earn all the classes. Nevertheless, if your idea was meant to be added on top of the current credit system and act as a kind of booster, then I think it is a delightful idea. I would like to see more credit earning options based around objective gameplay, but this would not be a terrible addition.
