I honestly do not get you guys. Xvm is a tool, a useful one at that. If people misuse it whose fault is that? It is a tactical tool in a very randomized arcade game and you want to ban it? 2-3 good player working together can win a match or you can focus down a great enemy player.
Yes, I have 20k battles in WoT. My past experience:
Yes, it can make chat easily toxic, when that happens I just ignore it. 95% the time chat is useless anyway, different languages, raging about artys etc.
Yes, in wot there is a winchance prediction based on stats, know what I do? Disabled it after a few times because it really can only tell which side has better players.
Yes, people sometimes throw games if they see too big of a stat difference, know what I do? I do my bloody best. Of course that is what I aim for in all of my battles unless there is a ridiculous mission. You dont give up and your stats will show it. "Stats mean nothing" Come on, that is simply a lie.
