Having the game remember what you last played as after closing the game, or changing servers, might be pretty annoying to implement. That adds so much complication to even just the menu side of things. Like, the UI has to know which UI version you're running (based on UI preset values of which we support 3 UI versions) and open specific menus based on that information, and that information is dependent upon multiple factors. That isn't an easy implement and I worry about things just breaking. Though its possible the things that I did for class config key selection would handle the majority of it. Not saying its a bad idea, but I just worry about the complexity of things in this engine and something breaking in the process. It might be more simple UI wise than I am making it in my head.
Some others and I did request the potential ability to have your model, hilts, etc also be within your build template pick, so that you didn't have to select anything else for that class.
