I've been lurking for answers to no avail, about this yellow progress bar over the minimap: I read the description saying "this bar represents the winning and losing victory point pool. victory point pools affect the amount of reward [..]" - basically what's victory point pool, how do we earn it, and what determines its increasing and decreasing percentages?
For example, if I'm a destro player, from our perspective of view (POV) do we have to try making it towards 100%, or should we reduce it towards 0%? I'm a bit confused with this, of what it really does, what's the goal of this, and what should I do in the teamwork in order to contribute to this progress bar? Sometimes this bar goes up and down, as shown on pictures, I've seen this bar within the same war session, that it was at 100%, then went down to 84% then it went up again 100%, and so on... so basically this is where my confusion comes from, of what determines its movement, and what's the goal here?
