Guild Wars 2

Planning on going a heavy crit build using P/P and shortbow and sometimes switching to S/P. I already use D/D in PvP so I figured this looked like a good route to go. Range is extremely valuable in PvE it seems especially with all the utility a thief can bring combined with the running around required.
This leaves me stuck in choosing between 2 armor sets:
Power/Precision/CritDamage and Toughness/Power/Precision

Any recommendations? Is the influence of range enough to warrant not getting toughness? Is crit damage actually even worth it?

I went with Knight’s insignia for my armor and rings. Berserker for everything else (weapons, accessories, ect). Personally I mainly use S/P in PVE and shortbow when there’s a big DE or I need to get back to recover. For PVP I go with D/P and shortbow. So far I’m liking it, decent toughness as well as some HP from my traits and I still do good damage and have a high critical chance (59% with the signet on).

EDIT: Oh yeah, my runes I use are Divinity.
