Is playing arena an effective way to build my collection?
I've played a few arena runs with varying success, and I noticed that on my last run, my 7 wins got me one keg, 80 dust, and 150 ore. I haven't been keeping track of the rewards for my less successful runs, but I think the keg is guaranteed at least. So I'm wondering whether I should just blow all of my ore on kegs for 100 each, or roll the dice on a 150 ore ticket, which is only better if I get more than 50 ore out of it. How well do I have to do for that? Is 6 wins already enough to get an extra keg's worth of ore out of it?
