Update: the news article has updated, and some keys should be mentioned:
“You will also gain the ability to sell unneeded weapons and dismiss soldiers to get even more bronze orders.”
“Unspent orders and weapon parts will be compensated - by additional bronze weapon and soldier orders credited to your account.”
The myth is, how much will they compensate? Like what if 1->3 ratio? But what if dismiss weapons/soldiers only get 1 tickets at a time.
My personal strategy here is: spend most of bronze weapon tickets to get enough amount of AVS/ZH29/FG42 to equip every active soldiers. Then stop.
Spend enough bronze soldier tickets to get enough infantry, and other key roles for possible upcoming squads (infantry soldier are very needed but too expensive if they are the same price of other soldiers). Then stop.
Wait for those left tickets to be compensate.
Also use academy to merge those roles dont need that much, like pilots/tanker/flamethrowers.
After seeing the news of progression system changes. All of my friends decide to empty all bronze tickets.
One of their screenshot:
I am going to leave only dozens bronze tickets, while spend ~50 bronze weapon/soldier tickets for each side.
Also, since they also cancelling retraining point, dont forget to use it (for 4/5 stars soldiers. For lower stars soldiers just keep them and probably after the update they will able to level up with bronze tickets)
BTW, Green tickets of this kind
should be cancelled.
And currently, the only way to get pistols/axe (except from drops) are via bronze tickets.
