Sorry I disagree increasing your level to be able to be able to play certain content (that you payed for) should not be locked behind an RNG grind, grinding should be exclusively for getting better/more desirable rolls on equipment and exotics and as for infusion costs, all it does is reduce your options of how to play the game, it doesn't actually increase the time or effort to increase your light level since that is tied to weekly activities (something you cannot grind) and as for your suggestion for Xur yer lets remove the only method of using the mats you spent time and effort to collect (you know the shit you actually worked for) to earn exotics and replace it with a system that simply increases your chances of winning the lottery because thats totally what "work for it" means.
