Well yeah randims will bail most of the time. Unless the fights are fun or the bet money is good there's no real way to combat that.Apex had to implement a penalty for leavers. Currently it's only in ranked and basically makes you wait until your banner times out.
Unranked doesn't have it yet and people will straight leave before a revive (only knocked). I don't usually have issues with randoms and meet a lot of good players; however this is one it the reasons I prefer rank in that game.
I don't think randoms will stick around to bet or 1v1 when they can bounce and re-queue back into full action, especially if they blamed their team on death.
