The game Destiny has a gear system that allows you to take a lower level gear that is rare and you want to keep and "Infuse" it into a higher level gear you already have - just need to pay a few coins and mats. I would love to for example take my CP 140 Valkyn Skoria and "Infuse" it into whatever random crap drop CP 160 head piece I happen to get from a drop. This would make me so much more attached to my gear instead of feeling like I am renting my gear knowing full well there is 100% certainty it will become obsolete an will need to freaking re-farm the same dungeons I have refarmed countless times already.
It should obviously not be cheap to infuse the gear together so they can make it outrageously expensive, but anything is better than havin to refarm every dungeon every time the CP level is raised.
Thoughts?
