Why should we even have to reset it? Would be easier, and better (imo) to just let us unlock ALL of the artifact mods and use them however we wish. You are limited to how many you can use at a time anyway so why limit us? The obvious answer is it's just another artificial mechanic for extending playtime. Earning the glimmer and spending time fiddling with your artifact. It's a crummy substitute for playable content but I guess it is what it is...
