Again, you're just wrong. No way around it. Let me explain.
you were speaking of the 5 second rules and how to stay out of it, the easier way to stay out of it and be ready to get serious mana regen without having to switch back and forth every 5 seconds would be to keep +int.
If you're not in a Spirit set, +22 intellect will not be gaining you a ridiculous amount of mana regen anyway. For example, in my 'cookie-cutter' set, with +30 SP, I have 88 int and 68 spirit. Swapping in my Twisted Chanter's w/ +22 (that's an extra +32 int right there) gains me a staggering 5 mana/5. Why is it so low? Because the coefficient for Intellect is based on its Square Root. Stacking Int gives diminishing returns to the gain in mp5, like I have said.
Mathematical example. let X and Y be the two values in the equation, one of which gets multiplied to the squareroot of the other. (NOTE: This is a very simplified form of things.)
Let's say you have 100X and 1Y:
(100X) * squareroot(Y) = 100
Here you only have to increase Y by 3 to gain an additional 100.
(100X) * squareroot(4Y) = 200
To reach the next multiple of 100, you have to increase your Y value by larger and larger amounts (+5Y, then +7Y, +9Y, +11Y, +13Y, ...)
So you see, adding Intellect is less useful the more you have. And hell, if you still have +22 int on chances are you don't have to regenerate much mana at the moment.
BTW, in the previous example, just a simple switch to Staff of the Friar (+28 spirit net) gives me a whole +17 mp5. Of course, if you don't feel like taking the effort to switch in and out of 'the oomstick', then go for it. Just be aware of what you're losing.
saying is that +22 intellect is good only for the 220 mana it nets you... but you are forgetting how much crit it gives you. that crit outdoes the 30 SP by quite a far number if you ask me. i'm not gonna lose that much crit % just to gain 5-10 more life point out of my heals !
1.) It's +330 mana. And yes, that's all it's good for.
2.) As I already stated, the amount of +crit is laughable. It's actually not as bad as I thought (calculated that %on chardev) but it's still completely useless:
In my same 'cookie cutter build', switching to TCS from Staff of the B. Seer gives me +1.8% spell crit. And and with today's average health pool, crit heals are almost ALWAYS mostly over-healing anyway. I'd say, and this is a generous estimate, that this gives my heals about 1% more effectiveness. This is no where the power of +30 SP...Which brings me to
3.) You don't just "gain 5-10 more life point out of my heals." +30 Spell Power gives you, more or less, and this is on Heal (rank 1), +50 to each Heal. That's about a 15% increase in effect.
run the numbers dude, you'll see what i mean.
Read up.
if you are a mage, shaman or anything that wants to cast and DPS the shit out of the others, SP is valuable... for a priest in healing gears, sp is valuable to some extent but its not worth jumping on the stat to begin with
Of all these examples, SP is most valuable to Priests. It makes everything (read: everything) you do better. Well, except wanding. That's Haste's job, and for a different discussion :O
only my renew are enough and with the occasionnal shield its even better.
And they're better with SP.
i'm often out of the 5 second rules and regening my mana while helping others and mana regen is important at that point. if i had to switch to 30SP i had been out of mana long ago !
I'll end by repeating what I said before:
+22 Intellect is not useful for mana regeneration. Unless your gearset is completely void of other Intellect, it will give you at BEST +5mp5. A nice juicy spirit stick will give you at least double that.
Switching weapons is a key part of any priest's game. Ask anyone if you don't like to listen to what I say.
