if you think about it the ge is already getting flooded with bots go to the yews at the ge or the miners guild on any world and there will probably be a few bots.now if theres a few on one world then theres prob more on other worlds; the ge is flawed and it is restritive and yes for awhile after the change the market would be chaotic at best but eventually it will settle.
The only negative thing with this is noobs will be confused, and bots will probably come back more. But Jagex says they can detect if someone is a bot, so that shouldnt be a problem
