So WG just yanked the Frontline Crews out of my Barracks?

DomoSapien: We've come a long way since Rampage mode, friend.
I don't have an answer as to why it's being done differently now, other than the fact that it has been done this way for quite some time now. Personally, I got confused by all the darn IS-7 crews in my barracks. Not sure why I need 3 of them. I finally just placed one of them into my 277 since I grinded up to my second skill on one of said IS-7 crews before swapping for a free-bia crew from my premium IS-2.

DomoSapien: Frontline was a big hit, and we will definitely be bringing it back! I think it's going to be a seasonal gamemode like Ranked Battles, but there were some performance issues with the map which caused even high-end machines to struggle at times. Long story short, it needs to be optimized, and we need some time to look at all the data and sentiments from the gamemode before we can figure out how to develop it further.

DomoSapien: Since the T34 and T34 B are technically separate vehicles, it's trained for the T34. However, you can put a T34 crew in a T34B or a T34B crew in a T34 without penalty.
