i dont have the opportunity to play TD as much as i could back in the 2014,-15,-16', nevertheless i always agreed among most players during this period that the AGT is a major balance issue in TD (unfortunately other paths have been chosen as a workaround back then, anyways
working on the agts would be something i would fully support and would be interested in testing those ideas when i can gather time for that.
My guess ahead on this idea would be that a skilled player <edit: in competitive 1v1 palys/edit> will still be able to select its agt and focus fire the tanks while in team games mass agt spam wont secure the flanks <edit: or cement the center/edit> too easily anymore, making more room for more advanced tactical position and importance of vector of attack /defense plays, ergo more interesting games
it might also give more room in the complex field of balance to bring back the unique TD multi queue dynamic many of us are still missing : an earlier 2nd mcv <3
