Lvl 50 ST, is the 4set supercommando bonus a must or better with 2set supercommando and 2set combat medic for longer energy shields?

2piece combat tech i think is better than medic, carbonize is up much more often than the shield, and you want the stunbreaker up as often as possible.

I'd say the four piece set is better, a 2% defense chance increase all the time is an impressive buff. Three extra seconds on energy shield isn't much considering its cooldown, and carbonize is not really useful for "end-game" encounters. If you were looking at only maximizing for flashpoint completion it might be worth it, but otherwise it has limited utility.

I'd say the 4-set bonus is a must for PvE tanks. It's actually considerably better than just a standard 2% defense increase. The bonus is 2% defense against everything, including against tech and force attacks. Those types bypass normal defense as well as shielding, making this one of the few ways to reduce those types.
