Were you buying refreshes everyday? It shouldn't take you to refresh cap (I didn't even know there was one) on the last day if you had the capability of doing all the feats. Bad RNG is one thing, but there's a point where you give up and try and go after another feat instead. If you found a node where your Dash or Ad Rad could go first, you could load up on ZA disks and just AoE everybody with Zuckuss and 4-LOM alive. Han kills you can do in 7 battles with JML, or fewer if there are revives on the enemy team.
Post your ally code and people can help suggest feat strategies for you. I'm guessing you either have an underdeveloped roster or you haven't been playing everyday. Because again, you shouldn't need that many refreshes. So if it's just the former, people can help you find a way to get the feats more efficiently.
