Kushi Stigmas are the only tradeable thing people can make use alts for, and you wanna make it even harder by removing even that option or what? How is that an issue, especially since its available for everyone?
Stigma, Events, Luna, cube-instance, stellium-vendor, lugbug-daily/weekly....
I bet I forgot some...
You farm lugbug, steliums, cubes on 3th 4th 5th etc account? Or what is your point.
Only stigmas are usefull via alts (not counting events but we get like 1 good one per year anway who gives a sh***t).
