Thats a polite way of putting it. Had the same on several games, big tier X's hanging back and getting slaughtered one at a time. Pretty sure young kids are playing these tanks due to the complete lack of skill and idiocy. You try to ask them to move forwards and you either get no response because they don't read the chat or they can't speak english. I thought the End User Agreement you sign up for means the official language is english and thats what you should communicate in? Seems this is not the case more and more often.
Also, seem to be getting a lot of games where you'll get a T-50-2 and a very low tier tank in a platoon completely scuppering any chances of a win. Or worse, a Maus and an A20 or something - I always report them for "unfair play" but I doubt anything ever gets done about it.
Played some War Thunder last night and I have to say, with the recent upsurge in retards in WoT I know where I might be spending most of my time now!
