Not well thought. Basically you want to exclude people running multiple of the same character or you want to prevent exchange of pretty much everything between characters in general. Personnally I see no point in this since I could not care less how fast people level up their gear. It simply does not affect or harm me (or you) in any way. However from your point of view [b]it seems to be nothing but jealousy[/b]. Most likely you missed a piece you wanted from Xur cause of insufficient coins and/or are stuck on your current level only because you do not have sufficient shards. With one character you can obtain sufficient amount of coins per week (>17 and even >23) provided you do the daily and a public event each day and run the weekly on 28 and of course nightfall. Also try to run the vault each week (if only for the shards you obviously need to upgrade). And yes with only one character you should ask yourself if you really need that item from Xur or better wait for something he might have next week you want/need even harder. TLDR: do more to obtain the required amount of coins each week. Even better, make a second character and you are fine.
