Please don't post the exact same thing in multiple threads. Thanks.
Another issue might be:
Using the stage 1 daggers (fear/vengeance) i've noticed that my landslide procs dropped to about 50% of what they are without daggers as combat.
I've compared it to another rogue in our guild on several fights. We have nearly the same gear, nearly the same hit aswell 14.4% for him and 14.7% for me. I used the daggers he used firelands weapons 2.6/1.4
His white attacks:
208 hit 214 crit
253 hit 252 crit
