Speed? Check, almost as much as a druid. Out of combat, anyhow. 
Stealth? Check. Good to get to places. Not so much for leveling.
Evac? Check. Good to get out of places. Not so much for leveling.
DPS that'd make a Templar blush? Check.
Mitigation to rival a Warlock? Check.
Avoidance on par with a Shadowknight? Check.
Heals to rival a Guardian? You know it, baby. As long as he doesn't have the Fury 'inherited' heal going.
I know I'm painting a bit of a bleak picture here, but I do love playing my troubador. We're not generally considered a particularly solo-capable class though, mainly on account of the fact that while we're near-indestructible against a single opponent, our speed is inversely proportional to the extent to which we need to exercise our invulnerability.
In melee, we tend to drop pretty quickly even against similar-leveled solo content (unless exceptionally well-geared). Kiting is slower since it omits our melee and close-range abilities, as well as limiting those which can't be cast on the run, however it all but eliminates opposing melee damage. Mezzing eliminates all potential for retaliation (or at least, if managed properly it can do) but slows us significantly more, since each damage cycle must be tailored to the opponent, and needs to wait for the mez (and often stuns) to refresh.
Now, compare our capability in a group. I increase everyone else's capability to receive, deal, mitigate, etc to a combined benefit of near 20% per toon (mind you I haven't done the numbers in ages, but they should still be close enough). So while I personally contribute relatively little raw dps, in a full group of 6 I not only pull my own weight as best I can, but give everyone else enough of a boost to amount to a 7th effective member. It's all about synergy, and unfortunately there's no synergy while soloing. Makes the effort to gain levels difficult in what appears to have become a primarily solo grind to 80.
Edit - MJK rocks; I assume that's where your forum name's from?
