I personally would like to be able to have a way for another tower to consume another tower for increase in tower level.
Lvl 50 flak (or any ember consuming tower) could be consumed for upgrade toward another ember consuming tower.
If they could come up with a way to let for example this lvl 50 tower be consumed by said lvl 75 tower and upgrade it… idk how the math would work honestly, but would see a increase in that tower level based off those resources consumed.
Same for all other tower types as well. Fire and ice shard towers being consumed for said towers and wood towers being consumed for upgrading likewise wood towers if any of those still exist
There should deff be a cost though, you shouldnt be able to get the same exact amount of what you put in the consuming tower, should only be a portion.
At least something would be achieved for these towers that people have “messed up on”.
I personally dont have many extra towers, besides a few low levels, thanks to all these players that kept me from making those tower mistakes when I started playing .
