Just to clarify, no one is listening to only one clan. This has been thoroughly considered. Initially, disabling the sell of potions all together was the plan, which would indeed be the best solution long-term with how much energy players have "these days". However, a compromise was made to still allow them for sale at 50%.

PS - if it were to have been level limited, it would be limited to 2000 rather than 3000 anyway. However, it is not the direction that has been chosen for this.
