Don't get me wrong - I'm not against them having 4mans that require 4 human players. It's just that I've done a ton of 4mans with only one friend and 2 companions so without any warning, this was a bummer. We did get past that one forcefield by being quick. Then we got to kill the boss at the end only to find out we were out of luck. Also - this instance happens to be required for the weekly. So unless I offer my healing services, I guess I am out the black hole commendations.
As to grouping. Honestly, we like the challenge of figuring out how to use all our abilities to handle the instance with just our companions. Also, when I have grouped with others to do flashpoints, I find that they always want to rush by and around. I like hanging with my hubby because he is cool with us killing all the mobs, all the bosses and actually listening to the story. Finishing, getting the loot and commendations is nice - but the story is too.
Anyway - it is what it is. At least now I know ...
