First, I'd like to ask again if it devalues your experience if someone gets a primal weapon drop on their first try, but it took you 10 tries to see yours drop?
Second, many people have already mentioned that SE plans to nerf coil later. (though we don't know exactly how much later) If they've already got people working on a nerfed coil, how is it a waste of their development time to use what they're already developing as an alternate version instead of a replacement? If anything, I think that would make the original development time of coil more worthwhile, since it won't be removed from the game.
