I don't know why everyone is so enamoured with Force Throwing lairs. I find it to be a waste of time, mostly.
I mean, it might become LESS of a waste once you hit your first +10 regen, but let's do some math:
Even at 4244 (something I'm a few days away from) and 600 total force, I'm still regenerating at around 1 point per second. (Reminder - write post for FP to regen in blocks of one instead of five).
That means to do the requisite "three throws for max xp," that's 15 minutes wasted for 4,000xp. Not to mention the process of doing it on mission lairs requires riding 300-500m away from the lair to do. So, grand total, you spend about 20 minutes standing there watching the grass grow to save enough FP to throw at the lair thrice - that means if you do it on three lairs, you've wasted an hour of buffs. I don't know about the rest of you, but I can polish off two missions in 20 minutes, both of which would net me a grand total of about 15,000xp. 15,000 > 4,000.
So for me it's really a question of "do I want to bust my ass for 15,000xp or stand here for 20 minutes enhancing the risk someone will come across me to get 4,000?"
IMO, Mind Blast 1 + Force KD is your best bet until you hit Force Lightning or whatnot.
