I have a 50 PT and have rerolled over to alliance...really I got sick of playing Huttball all the time. Oh and hey Trooper has cooler armor IMO. Anyhow, I have noticed a significant delay on Motar Rounds or what ever. DFA has a slight delay as you fly in the air but its really just about an 1/8th of the bar or so, mortar I am getting damage at the 1/2 point. Its really hard to use in a kenisthetic PVP match.
And yes the pyro/tactics trees are the suk.
