My main motivation when playing Card Hunter is to collect gear. Having said that, then the most efficient use of MP is to play just a few games per day as fast as possible and not sweat the outcomes. With the ELO system, I'm going to win about half of my MP matches over time. Period. There's no reason to worry about individual outcomes too much. My approach is one of the (possibly) unintended consequences of incentivized PvP. But here's what I think is a little odd: If I'm interested in collecting gear while playing SP then it DOES matter to me if I win. A loss is just wasted time, rather than the "price of admission" that it is in MP. So... I care if I win SP. But not if I win MP. Weird.
