a lot of opinions concerning the aegis set; just search the forum and you will find many threads/posts on it.

i currently use the aegis set on my atrox and it does fine. since they are nerfing the 3 piece borg / maco set up i crafted another aegis set, just in case.

i would save my ECs because if you have played that long you should have most of what you need to craft the aegis set. even if you don't, it does not take that long to gather the material.

however, if you are loaded with ECs, that is certainly a short cut to acquiring it.
