INORITE? That truly is probably the only time I would suggest not regemming. This is, of course, assuming that your next piece or two will be better with AP gems and not Agility gems.
1. a. I use a TotS macro that allows me to tricks without losing downtime on the boss. b. /cast !Stealth so that I can mash it with it only turning stealth on, not off. c. Poison macro that will instantly put on instant/deadly on my weapons instead of clicking them and then applying them manually. d. more of an escape macro, /cast Cloak of Shadows /cast Vanish. e. #showtooltip Mutilate(Rank 6) /startattack /cast Mutilate(Rank 6) /run UIErrorsFrame:Clear() mutilate macro that allows me to autoattack without right-clicking the target and no errors. f. Cold blood macro that I use for my envenoms, gives them high crits for more DPS! yay that's it really, I have some for pvp that aren't used for pve so I won't list them. 2. I use SliceAdmiral which keeps track of all my timers and my combo points. And not sure if you meant only rogue specific, so I'll list some other ones as well. Mods like DBM, Omen, and Grid are key to succeeding in a raid environment. 3. I'm not sure how to attach the spreadsheet. 4. Basically I will mutilate to 4+ CP, envenom, mutilate to 4+ again. At this point when the envenom buff is still up, I want to wait until it's just about to go off and envenom again to get the buff again. But if the situation comes and say my energy is about to cap and I have a couple seconds left on the envenom buff, it's better to just "clip" the envenom buff and start it over. Another good strategy to ensure that I get to 4+ CP in time is to TotS in order to gain +15 energy(2 pc t10) giving me more energy to mutilate! 5. I know idk why I leveled enchanting, part of the reason was to make it a lot cheaper when I leveled JC. Once I get the gold, I might level engineering, but for now atleast I have two DPS increasing professions. 6. I do click those, mostly because I pretty much never use them in a raid setting. I plan on changing those. 7. The way I monitor my ticks, as stated in what mods I use, is AdmiralSlice. Really helpful for me because it stacks all of the timers in one small area.
