2.4 Mana Regen sweetspot, revisited
This is… annoying. In my last long post, I told you the sweet spot for mana regen was when your spirit was twice your int. Wider separation, close the gap for better increase of MR, and if closer widen the gap.
The rule – move toward the sweet spot – still applies. The problem is that I’ve got a conflict. Someone on elitist jerks (and I regretfully do not recall the individual) posted an elegant, SIMPLE mathematical proof that showed the sweet spot is where INT is 2/3 SPI. That’s… just a little different from what I got. I got MINE from empirical work – created a chart with a whole bunch of numbers, and crawled through looking for the best change.
I’ll be revisiting it – printing out not only a chart, but letting the autocalculations determine the ‘better’ option for a given increase. For now, though, I’m going to say that given a choice between math and bleary-eyed scrutiny of a screenfull of small numbers, trust the math. If your spirit is 600, aim for an INT of 400.
Oh, one tiny, tiny point here. Apply a braincell or two. If you’ve 600 SPI and, for example, 500 INT, don’t just strip 100 int. That’s 1500 mana and a bit of spellcrit. Worse, 600/500 generates more mana than 600/500. Given a choice between boosting more INT and more SPI, go for the SPI. Maybe – MAYBE – if you can swap some INT for SPI, you can go ahead and do so. But don’t just remove INT for “optimal mana regen”.
As a last remark — I foresee Draenic Wisdom elixirs becoming really, really popular. Add the mastery as well and most level 70 casters will see mana regen rates comparable to if not greater than what they can get from Mighty Restoration – but with extra stamina, agility… For a lot cheaper, at that.
