I can get 23% from free XP and 22% from national blueprints. That leaves 55% to be acquired with free XP or gold. It will then cost 27.5k bonds, 30,250 gold, or somewhere in the middle. I can narrowly afford both of the above, but need the smartest strategy of spending mine.
Possible uses for gold:
Betting in the upcoming auction/black market
Buying normal gold deals (like the recent ShPTK for 9,500g)
Buying premium time
Possible uses for bonds:
Betting in the upcoming auction/black market
Buying stuff in this year's ranked shop – exclusive tanks or skins
Betting on clan wars reward tanks
Buying t10s or t8s in the normal bond shop
Bond equipment
This makes bonds quite a bit more valuable, but I need some gold, if only to extend my premium time. Thinking of spending 22k gold (40%), filling in the rest with bonds. I am aware that buying free XP for gold is a better deal.
