EC was nerfed substantially before 2.0, SM was completely doable with anyone. Yes, it is indeed bizarre why it never was part of the group finder. But, as always, Bioware knows better than us, amirite?!
Krewel how often did you pug? Pug you see is an apt term as the average intelligence level of a pug is the same as this little fellow right here.
It's amusing in a sad sort of way watching all these group finder Ops fall apart on SM TFB and S+V. I think of it as vindication that EC didn't belong in the group finder.
