Been playing this game 10-15 hours a week for over a year now. (Started in Feb 22). While it was fun and almost addicting at first. Once you reach a certain point it becomes almost impossible to advance more than one vehicle in a tech tree of 60 or 70 per week. On top of that the cost to buy the vehicle is then undermined by another 30% cost to "train" your crew. Couple that with increasingly decreased rewards for both kills and victories and increased costs makes the economy predatory. Even after spending almost $200 in game and using 3 high tier premium vehicles in the US tech tree im struggling to get past BR 7.0 due to the cost of repairing your damaged vehicles making it so that you might earn decent research points but you usually lose currency in top tier matches if you dont do exceptionally well
