Hello,
We are not planning any of such changes and they would definitely go against classic experience. We have already made many changes to the game that make it easier.
However, our recomemndation would be to use a socketing for the last manastone slot, if you say that you spend many millions to re-insert the stones again and again. It might be that getting one socketing would be cheaper than buying new stones.
They are tradeable and you can find them on the broker, in the private stores of the other players or buy it directly from someone.
Hope this helps.
Have fun in game!
