Current best method to grind law tomestones?

I'm sure we will see Bismarc/Ravana EX mercs soon if they aren't present already.

I wish I could grind Tomes, my DPS queue times are 30mins+. I hope in the coming days as more people get level 60, queue times will drop. I've just been doing the daily roulettes for tomes. I'll have full gear before alex for sure. But I guess it gives me time to finish DRK to 60.
