This statement is the most false statement I have seen all day long.
Force is BY FAR the slowest stat to regen in the game, if you run out of Force you may as well just /quit because you wont be getting that force back anytime soon.
My friend that I play with has played our main raid healer for every MMO since 1999 EQ and He has played a Sorcerer, Operative, and now a Commando being a main healer for all 3.
From watching him play and what he says the Commando is far and above the better healer of the 3, followed by the Operative, and then way down at the bottom was the Sorc.
At 50, yes Sorcs get better, but their mana issues are much more problematic than those of Commandos/Scoundrels
My sage never runs out of force because I can kill myself to regen force...
My Scoundrel never runs out of energy because I rotate my energy based heals with my free heals so my energy level never drops below 60%. If I started spamming big heals I would be out of energy in 8 seconds and then i'd be screwed.
