I have.
I didn't just admit it, I've shown the math on exactly how much it is or isn't, I see no reasoning behing your logic besides "8 for 50% feels better than 21 for 100%"
No, I don't run with quicken all the time, you are correct there. But in the times when mana efficiency actual MATTERS (the quests you mention, perhaps?) - I do run with it. Great, you have more mana efficiency in braindead easy quests, great? I tend to dump mana like the plague in those quests for no good reason other than to see pretty pixels on my screen. Meh? My gut goes opposite yours.
As stated above, they're the only two quests that matter. Have fun in WW efficiency.
If you don't have aggro often, you're not doing as much damage as you seem to think. If you're not regenning mana, you're MUCH less efficient than I am, in ALL quests.
How can you obliterate things in general content and not pull aggro?
There is nothing else to say. People can draw their own conclusions, I just want the CORRECT information out there for them to decide (IE. it's a very close race between the two on efficiency, and maximize comes with benefits ^^)
We haven't even discussed when you need to toss out a heal (unquickened, apparently) and have to untoggle emp. healing not to waste sp ... Or you just have such good micro you can OBLITERATE melee, untoggle/toggle metas, AND cast VERY slowly? (and while doing all that, somehow keep your DPS up to remain useful?)
