When I train Herblore legit, I usually click on last vial so I can click herb right next to it. Maybe 5-20% chance of clicking the last vial would be good. As long as it is not 100% the same thing every time I think it will be a little better for anti-ban because 100% the exact spot is more likely to be caught, even 90% same spot is better with occasional last vial. Let's see if anyones opinion is similar, I may be wrong.
