How about some random powerleveling tips...

My Sorcerer is now 29, the Powertech I'm leveling with Callsign is now 25, I'm now up to Legacy Level 41, and I've been playing all day and need a break.  So it's time to write something (brief, dinner's almost ready).

How about some random powerleveling tips?  Here's a few off the top of my head:
-Unless you can get a premade, never bother with Warzone Matches Won daily quests--but DO get and finish the Warzone Matches Played quests, as they're quick and easy.
-You can (and should!) buy your way to 4000 affection with most new companions (depending on how they take gifts--Ashara for Sith Inquisitors, for example, won't like anything you give her if your character is female and isn't worth the money you'd have to spend unless you have tons of it).  This may be difficult to do on a first character on a new server, since it costs ~20k minimum to do per companion.  Companion scenes on your ship are potentially worth lots of free experience at the cost of the ~20 minutes you'll have to spend feeding gifts (watch TV, listen to music, and/or multitask as much as possible while you do this if you want to save time)--I recall specifically gaining literally an entire level at one point on my Marauder talking to companions on my ship.
-Bonus series, for the most part, can be skipped.  I'd encourage assessing how easily of a time you're having leveling once you finish Voss and do one or both parts of that bonus series if you're behind in levels.  If you're having trouble here and there, aim to start Corellia at level 47.  If, however, you're doing something like leveling as a tank spec and are basically unkillable with no downtime, don't waste the time and keep steamrolling through planets.  I leveled my Assassin Darkness spec, finished Corellia at 48, did the Ilum planet quests and got about halfway through the Belsavis bonus series before I dinged 50.  In general, aim to do that: finish 50 on or near the end of Ilum or the Belsavis bonus series since those are things you'll need to do at 50 anyways.
-Bonus series aside, do every quest and bonus that you can on the way through a planet.
-Flashpoints are optional, but probably will slow you down.

And that brings me to dinner.  Mayhaps I'll continue this another time.
