Suggestion on new update to Towers.

I saw the update to the tower system in PoE2. I think this will be a great change to towers! While addressing this with friends, i came up with a idea they thought i should share on the forums. Just a thought, and im sure you guys have thought of this, but id be a fool if i didnt share with the class.

Would it be possible to make the tower system free? Follow me here, Say you are clearing T15 maps, Would it be possible to make towers a free fee for a basic map at the highest tier you have cleared? While also still having the functionality to boost the tower with a blue or gold map if you would like to juice the tower up a bit?

it wouldnt cost you anything to run the tower and plug in a tablet if you choose to do so, eliminating the cost of the tower if you are just trying to clear it and move on early endgame, all the while still keeping functionality for later Endgame.
Probably did a poor job of explaining that, and im sure someone brighter than me has thought of this. Just throwing it out into the ethos.
Love the Game!
