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.
Also, you should buy random weapons using your bronze orders in the campaign where you have the highest rank (or any completed campaign), because there is higher chance of getting higher tier weapons (weapons with more stars). Then, after the update, you will be able to sell these weapons for bronze and use the bronze in any campaign.
