As most people may know, the Beyond update will include a new node for Decent HS. I've been thinking that it would be nice to have a similar node for Kishin, right now people with a Kanna mule have a huge advantage when it comes to training or hunting for rare drops.
Running a Kanna mule means you need another computer or you have to break the ToS using a virtual machine.
Another solution that would work at least on reboot is to add Frenzy Totems to the cash shop for a price similar to Hyper tele rocks maybe, or make it Kanna's link skill. But I prefer the idea of the decent kishin node better because it would only affect characters over level 200, not every link mule/secondary character you make.
