I think the last spot for F2P to add is somewhere in the security stronghold?
For members there's spots like Hill giants in Zeah where no one ever is. Experiments. Chaos druids. Bandits for high levels. Just few possible ideas.
Think accounts maybe last a little bit longer if they keep moving around.
Yeah it was weird.. Anyways worked fine when items were in bank instead.
Probably will just test out more and run until this account gets banned.
Edit: Honestly if you just sort out that bug it's pretty sweet. If you add a few more members options/training spots, should be premium script.
