I've searched answers for them quite some time now, but after some mentally challenged rogue in a PuG went very verbal about my specc.. even as far as logging an alt after ignore, I thought I'd give it a try and get an answer from someone how knows it a bit more in detail.
I'm currently in mostly level 251 gear with a few 264 in the mix and usually pull 11-14k DPS in ICC 25 if I can stay on the boss all the time so it's more about curiosity, not bad DPS.
1) I'm using the standard muti PvE specc with the only exception being having 2 points in opportunity instead of relentless strikes. I usually make my own speccs and check only if there's something really wrong with my performance. So the question is why is opportunity worse? Muti is something I use pretty often, it hits hard and 20% more damage to it sounds like a big deal. Also how big is the difference?
2) Why is it advised to only use 4-5cp envenoms? It just seems to me that the bigger uptime on the buff and potentially not wasting one CP would be worth more than a slightly higher damage envenom.
