Tell me, how are you going to distinguish me pulling out my LAN cable or disconnecting from my Wi-Fi or just closing the game from a disconnection actually happening because of my shitty Internet or the game crashing so I am not wrongfully punished?
This is my personal opinion, but if YOUR internet sucks it is YOUR problem then. If you play a (ranked) online game, make sure, your internet is working fine before. If the game crashes it is honestly another point of view, while I have to say that my game NEVER crashed ingame. Only while receiving my loot after the game a few (about 3 times). Otherwise I never had any problems in this area. I am also pretty sure that the game can get the knowledge if it diconnected because of Internet issues or a Bugsplat.
Not to mention some pissy 12 year old with a bad connection might try and sue Relic even if he can prove he was wrongfully punished on a few occasions.
Nonsense, what should he sue Relic for? Missed points in his Elo? It's not like anything is being taken away from him, he doesn't lose commanders or skins or whatever... only maybe an hour of the possibility to play ranked matches with others. I am very sure that this is already stated in the End User Agreement for playing online as banning persons from multiplayer for extremely negative behavior is possible without a doubt. And in this case you are really taking a big portion of the game away from the boy that cost real money.
