Just go and spend all your bronze tickets NOW!
All weapons available from Logistic is >=T1. So even if at worst, you wouldnt lose anything. But Logistic Bronze weapon tickets also can give you more than base tier of weapons. That’s how you get more value from.
Also, if they keep the equipment price unchanged, even the med pack will cost 1/2 silver tickets! ~12500 CAMP XP for a medpack! Now it’s only 5000 CAMP XP!
Also due to default weapons (those come with soldiers) will worth NOTHING. But now you can still disassemble them, 10 parts for 1 bronze tickets! Just disassemble them all! And keep your parts and wait for the update to transit parts to bronze tickets.
