PVP: As a Summoner, pre-3.0, I always stacked Crit > Det as my secondaries.
Post-3.0, I've stacked Crit > SS > Det as my secondaries in PVP; however, I'm starting to wonder if I should stack Crit > Det > SS in PVP since we are a little less dot reliant than we are in PVE (thanks: purify, enemies dying before the full dot cycle, etc.)
Det would also help boost Ruin spam and the PVP skill damage, which may be more of a boon than SS speeding up the kills.
(Crit is still king, of course).
Thoughts on the tertiary stat?
