If you are able to:
Wait for ranked to get the kpz 50t or the concept 1b.
Save your Bonds up for clanwars auctions.
I really recommend this because the Tanks you get from these Events are way more worth it, but if you don’t have a t10 to grind ranked/cw save your Bonds until you get to grind this event.
This is my Opinion and i was way more satisfied with those special vehicles compared to the regular bondshop tanks and i wanted to talk about this because its a question thats asked a Lot.
