I only did portal twice when i was gold tier. 1 time was fury, 1 time was gore. So 50-50. And no i did not strip naked, stand on my head and dance around. I had also gotten more payne when i was gold tier than a plat friend. Its all random. I think im ok w luck, so i dont usuly get long runs of fury. However, in calculating how much energy i need, i use fury. This way when i have extra energy at then end, im happy. So far, after running 40 toons, including no tier ones, id say its all pretty random though yes, payne is very rare at no tier, bronze tier, and probably about 1/5 to 1/3 at gold tier. At plat tier, he can be every time or there can be five furies in a row. If you are getting lots of fury, have someone else spawn the zone. Every player has different rolls or use someone else's if yours is bad.
