What I hate about it is that you only get to use a generic tank with a generic crew. So all that time spent building up exp on your crews is a total waste in this game mode. They already made it to where you can just buy exp with those crew training books, now you don't even need it. At least Front Lines you get to use your crew and tanks and earn exp so it's worth the time. Maybe next we can just buy the crew skills straight up. Then you could start tier1 with every skill your crew could possibly have! No effort needed! Reminds me of a line from The Incredibles, "Once everybody is super, then nobody will be super."
Hopefully most will just stay away from this game mode and they will get the point.
