Finished my PT Pyro a couple days ago as my 7th 55. Due to legacy gear awesomeness I ran as a sub in one of the guilds DP HM groups last night. Gotta say coming from Jugg/Sentinel/Assassin/Shadow I was a little apprehensive about my effectiveness without a significant 30m gap closer...
...But it was never a problem, couple times on Raptus after being teleported I missed the Intercede + Leap combo on the Jugg, but to be honest it didn't feel any worse than my Assassin.
Throwing in my 2cents as a brand new powertech alt, Jet Charge would be nice - but theres no way I would trade other skills like Grapple and Hydraulics for it. It's just not needed.
