So i think that having Xur arrive Friday at 5AM and leave Sunday at 5AM is really inconsiderate to people who work on the weekends or people who are very family oriented. Myself, and many of my friends play 4 days a week. Those days happen to be Monday thru Thursday given our respective jobs and family structures. This has caused me, and i suspect many others to miss out on xur exotics and now the exotic shards that are necessary to upgrade weapons and gear the rest of the way. I do not believe that you should have to play Friday or Saturday to have fully upgraded gear and there should be an option for upgrading your gear without Xur all week long.
