How many times have you not used any of the boosts in a campaign mission? Many times right? I've been there too.
So while I was doing a grinding marathon in Big Boy, I noticed how I have 3 unused boosts left. They're repair kits and I can't use them since my HP is maxed out.
This is where my suggestion comes in:
FOR EVERY UNUSED BOOSTS IN CAMPAIGN GIVES YOU 3000 CREDITS
But if that's not enough for you high level superiors out there, it's enough for a re-rolling scrublord like me. Although this could be adjusted in accordance to the level of player. Or 3000 is already a good number irrelevant if you're a high level or low level player.
That's all. Be sure to add context if you have one.
I've said this once, and I'll say it again.
Please remove the feature of box prices' increasing each time you buy one.
