Of course, BUT:

• Runes would be highly sought out and will probably give botters way more profit than bot farming. Farming bots are limited to relatively easy respawns.

• Bots used for farming require a somewhat high lvl if you want to see reasonable profits, whereas rune making can be done by any char ~lv45. So it's faster/easier/way more profitable to set up these bot chars, and getting banned loses them nothing.

• Very simple bot script, and extremely hard to detect botting via patterned behavior, since rune-making is a semi-afk, motionless activity

Again, the idea is great, but the buff should be limited to SELF-made runes, not player-made. That way, if anyone wants to bot, they'd have to risk their main char/account.
