Duel boxing going to be particularly abusive?

Have a friend DC or forfeit 1 round into a game over and over again to gain booster packs quickly

or why even do that?

Since the game is free you could just have a 2nd account and fight yourself
From a networking standpoint it just looks like you're playing your brother who is in the same house

Will this be stopped or will it be handled like how legit players get temp banned from Diablo 2 for leaving a game too soon after they joined it?

The only other option is to adopt what Team Fortress 2 does and limit the loot per week

Something I honestly despise, but was put in place because of a few bad apples who exploited it

If someone has an actually good solution I'd love to hear it
