I played only the supremacy needed to get plat each week. Try to run a Rushdown or two each day, and complete plat bounties running other activities. I have only been looking for one weapon in the rewards, Taraxipos with a better roll than the one that I got last year. So far, no luck, and I honestly dont expect that I will get it. RNG weapon drops during events suck all of the life out of them when you never get what you are trying to get, that it makes me not even want to try. I cant play PvP Supremacy with my friends who are not Warlocks, so if we have more than 3 clan players on at a time, we cant do either of the GG modes. The fact that class items are required also is a big miss, since it rules out any builds with exotic class items for the event.
