I’m sorry, calling the Aeon shields the worst in the game is just completely and unequivocally incorrect. Smaller shield radius does not mean bad, that can actually be useful in some scenarios such as getting nice shield layering.
Also, if rebuilding t2 shields into t3 is something you’re needing to do on a regular basis then you’re probably doing something else wrong. T3 shields are not always better than their t2 counterparts.
