Aeon tmd have to be played the exact opposite way as all other tmds: close to the target you need to protect.
It has pro and cons.
Pro:
Deflect all at once
Deflects Cybrans and all over 2HP tmls (com tmls)
Deflects billy
Cons:
HP
Limited deflexion radius
Overall, i think the aeon tmd is weaker then most others now that the com tml was rendered useless.
It's probably the worse TDM against MML and cuisers and you can even go thought it with 2 tml using a delay combination
IMHO, it's part of the game mecanics and overal balance
