Deserve as in meaning getting the roll for that round of loot. There is a guaranteed reward, whether it is good or not. If it takes hours, then it takes hours.. I don't see why it would though. I usually run it solo up until Crota then I get a group. Once I'm 32 I'll just be soloing the whole raid every week (assuming I actually take the time to rank my Ghorn, ever since I upgraded it I've been on gta). You've got all week to do up to 3 raids, no need to rush it. If you don't get it one night try the next.. It's not like it's a rush.
