Had a wager system, where you could choose to double lift gained from a win, while doubling lift loss from a loss, but you could only wager BEFORE seeing the enemy.
That'd be nice... When you're needing 1k to move up a single rank and it looks like the entirety of players from 1k-4k are going to fail to hit that goal, an extra boost sounds really nice...
Not sure. It can be great way to help you move up in tiers, but it can also ruin any chance of you having a good ranking and probably piss you off as well. Of course you could just not bet, but where's the fun in that?
