It's trash, the game will eventually stop giving you VC and force you to buy them with $$. Unless you're the pro of the world like. Captain. Apparently he gets 500-700 VC every single game. You're cool.
I know this is a dirty word to most "gamers", but you have to put some EFFORT into the game. You're not going to dominate right out of the gate, and be a starter. Like most actual rookies, you're going to sit the bench a lot, and get incrementally better. I know that's unheard of in the world of paid unlocks, but it's a marathon, and not a sprint.
