Bonds will be massively used in the future and they will always stay as a reward currency.
Bonds are an encouragement for in-game activity of different kinds.
Players will be able to buy a lot of things with them, from camouflages, some specific HESH rounds, to various Premium vehicles that were withdrew from sale, etc.
So I ground the Caernarvan out almost completely playing Frontline and now I am grinding out the Panther II on FL as well. I had a 278k credit game in the Pii last night, what a fricking godsend its been to salvage shitty tier 8s.
I just realized, I haven't played a single random game since the 5x weekend, just Frontline. It has problems, but it's a breath of fresh air for the game. It needs a couple of more maps and perhaps different tiers at different times (tiers 6-9), a few performance tweaks, something to discourage spawn-camping and that's pretty much it.
