The Jackal Mastiff is awesome as are the new missions for the KDF.
Wardan Gazzan's voice alone is awesome, especially when you ask him if the prison facility is secure enough to keep the newly-captured prisoner. It shows how great the Voice Actors are compared to the older things like the Fed Tutorial and that Undine posing as a Klingon Captain with his Batman Begins-styled deeper voice.
There's only one thing I can think of which is better than one Jackal Mastiff.
Two Jackal Mastiffs. But I'm not going to ask the Devs for this because it would be greedy. Next, one of the SpoonFeds would see me in a Ground ESTF with only two Jackal Mastiffs and a really big stick and then come straight here complaining about how the Klinks new ground combat pet is OP and 'ruining the game for everyone!!'. rofl.
I Got mine, summoned him, got a dialog box and even before i could read a single dialog box he vanished and went on a 4 minute cooldown. Seriously lacking if you cant even summon one before you head into combat.
the same thing happens with every single combat pet in the game. Try summoning your photonic fleet before you get into combat.
You have to have an enemy for it to aggro on or it goes away.
Yeah the first group of Mission under "Empire" in you list is doable. The very starting tutorial mission when you start the game can only be done on new chars and doesn't show up on the list, but its the one where you go from 2nd officer of a Klingon Bird of Prey to its captain, but the ones after that one you can do with your old chars as well. The one where you get the Jackal is the one that takes you to Rura Penthe. To me that one is great overall from start to finish.
