I don't know, putting bots in the tank and make it a one driver tank seems like the easy solution for me. For a game of this proportion I would be seeing to have very realistic features in every aspect. Please don't get me wrong, it is realistic and professional, and I will play it no matter what, but it would be cool that it could be implemented in every asset like tanks and hopefully even later planes.
I've played many times in PR with 2 team tank, and also in WWIIO, it was as pro as it can get. Formations, tactics, strategy, cooperation, work together and such and it's the best thing ever. MOST people do want to work together.
Idiots can and will be everywhere, noob squad leaders will do whatever, will also be AFK in very important parts or just quit battle randomly when attacking or defending, normal soldiers taking important kits and running off, commanders pushing every button randomly. Also there will be noobs in one man tank screwing around, going wherever and not paying attention, or bailing the tank in the middle of the map... and that is worse...
Everybody intentionally or not will **** up, will be AFK to take a **** or because wife is calling, it can happen to anyone. Don't just stigmatize the tanks. Any person that is AFK or running around, doesn't matter if infantry or tank can ruin a game.
Plus, generally, it would be up to the players, Squad leaders, Commanders and ADMINS to remove players who are not playing fair, not following the rules and disrupting team play. If a person is messing around, Admins should be notified or could get a vote kick from the people. If you guys can't trust fellow player then go play World of Tanks or COD. Games like these is where you depend on everyone, and if it doesn't work, you look for a solution (vote kicking, telling admins, etc.).
I completely understand that there is a lot of work involved, and it is hard, and devs may not have enough time, and for sure I trust their judgments as to what is best for the game, but I would love it if they could try and see if it works.
