The mission line to obtain the sword fragment and stop all Gre'thor from breaking lose at Captian level is AWESOME.
The ship battles are intense and hard. The ground battles are amazing and involved. The scenery changes so dramatically. It was like playing Diablo II more than STO. All who were involved with that line deserve huge acclaim. It was a welcome break from all the monotonous grinding and fairly normal missions. It is easily one mission line that should make the Feds jealous because it is so deep and fully realized and NOTHING like anything they get.
