I know it has been rejected many times. But i think if you could add it only for gear, it would make the bosses runs more profitable. Especially for newbies who do their zakum run every day. if you had the chance to sell a z-helm in the shop would be great. even at ht, where it is currently difficult to find a buyer, it can make the runs more profitable again. Pro: - More messos through Boss-runs - better mesos for newbies - Price increase Helm scrolls
Yet you suggested it once more, without addressing the core issues that are brought up around SoK, and curiously only mention "pros" without listing a single con (of which there are many.) It's a no from me, regardless of whether or not they are possible to add in the first place (v62 vs v72 content etc. etc.).
I'm not quite sure it would increase meso making from boss runs. I see the drop of meso making in boss runs is directly from the lack of new players having a demand for those items. SoK wouldn't fix that in Royals current state. SoK wouldn't fix anything really. It only accelerates the ease of obtaining untradeable items. Items that Nexon designed to make money off of us should not be in the game that has Vote2win or RWT/Vote abuse issues. This would just give players access to trying to obtain godly untradeable items through other means rather than grinding boss runs. Gameplay should be rewarded. Not pay2win mechanics.
