There was a period during Preview testing when people felt the balance between augments and non-augments was "just right". Basically, there was no clear choice what was better - Yes, augments would be better for some builds and circumstances, while a healer or striker companion was the superior choice at other times.
Basically, not having a single "BiS" choice was a clear sign that the balance was "right" - just as it should be.
Then we got a change, which significantly reduced the DPS of strike companions and the healing from healing companions - one companion that previously healed for 15.000 HP every now and then would now heal for 150 HP.
With one stroke those companions were just made irrelevant - exactly when the consensus was that things were "right", and now there is really not a single good reason to run anything but an augment.
Upcoming fixes look good...so, not giving up yet...
