thanks for sharing us your insights...
as we see every good suggestion might be a subject for abuse. and regarding bots, even without this said npc.. if people wanna abuse the game they would. they can bot on chivs,seeds,berries,speeds,etc... and the most controversial item for botting way back a month ago are "rat tails"... and many people already get jailed/banned coz of doing so. bot are already rampant if they where coz the majority doesn't know how to bot. so its still serves the intention of the majority.
if its only gonna token to zenny npc, well... nvm coz its helping the token to shrink even more.
lastly if im gonna donate, i will donate for items like capes and artifacts etc... since it more cheaper to donate them in real money than buying them in tokens.. thats why most donators does this to profit more tokens rather than donating for tokens, but in the end.. they end up waiting for a decent buyer for a long period of time. and some of them even sell their stuffs desperately at a lower cost and not resulting to profit coz only few can afford them. i believe adding more tokens in the market will help the fro's economy to ease a bit..
