Exactly, Que times at Lvl 50 aren't to bad even for dps. But unless you are a tank queuing for Lvl 10-49 flash points are gonna take hours and for people like me who can only play a few hours each day that just isn't an option. And even with the legacy co buffs levelling only on WZ's just takes to long.
Trust me. It takes hours as a tank as well. And after a couple hours go by (during primetime), its not worth even trying anymore.
You know, I seem to recall devs saying they thought cross server LFG was a "last resort". I say its high past time it was in there.
