Castrum grind might stop me from subbing

[Seregil]

do you know that other dungeons giving you tomes too?

In fact, when it comes right down to it, a Praetorium speed run (one tank, one healer, six competent DPS) where you skip unnecessary mobs is a more efficient (and less troublesome) way to earn the same number of TOMESTONES (not tombstones, stop calling them that) as your Castrum speed runs.
