This is also in reference to the poster above me.
I think he is trying to get at the priority we put on the Straighter Shot proc.
For me I consider a few things when I get an SS proc:
1) are my dots expiring in the next GCD?
2) If so, can I reapply both dots before and still make use of the SS proc?
3) If all of this is good then I will prioritize dots over SS proc
If it does not satisfy all of these conditions then I will SS before applying my DOTs again.
Also as your crit scales into late game (with full BiS gear and acc cap (plus food) your crit % will be over 40 through an entire fight). As you get more crit, the priority on SS goes down.
