This website cant be accurate at all? On a 99 parse on Huntsman Heroic its telling me that both us rogues missed potential 14 casts of shadowdance even though I had 99% uptime (got lucky and didnt get debuff to run out or anything) but I never had more then 1 stack of shadowdance other then at pull obviously. Ontop of that saying I only had MoD on cd 60% instead of 95%? Considering I have it bound with my SD and I use it on CD this can't be correct.
EDIT:
Can confirm it is not a good measurement. The top 5 parses in the world all have this "major" warning also and says they can use shadowdance 50% more often? Don't know how they messed that up so badly
