This is just empty speculation. Edos have shown better feats than their alive counterparts, especially Hizuren and Minato. The fact that despite the 'Life and Death' situation - his wife ended up dying - he didn't use it, means, his reserves are pitiful to support such a fighting style. Another fact supporting it is that he possesses the Toad/Frog Contracts yet doesn't possess Sage Mode.Who said that EDO's will get a speed boost?
Do u really think Minato managed to use shadow clone only because he is an EDO and never used it when he is alive?Every EDO feat of Minato = Base Minato feat as long as he don't need Kyuubi's chakra to perform it.
It was clearly stated in manga that EDO's are simply weaker versions of their alive forms with unlimited chakra.
Weaker Versions, given the vast discrepancy between Hizuren and Edo Hizuren feats? Yeah okay.
