This is a guest post by Chloebelle, a Resto Shaman helping you decide between MP5 or Int as the stat to aim for
There is something that feels really dirty when you start stacking intellect. Like that’s what you would do if you knew nothing but what was on the WoW Tool Tips.
For so long MP5 was vital to ensuring you could last an entire fight. Now, thanks to Replenishment, intellect has stepped into the spotlight.
Replenishment restores .25% of max mana every second. If you have an 18k mana pool then you are getting 45 mana a second or 225 extra mp5. If you have a mana pool of 20k then you are getting 50 mana a second or 250 mp5. That is a lot of additional mana.
Solely looking at gems, check out what intellect could do for you:
Ignoring socket bonuses – if the average person has 7 sockets (not including meta) all gemmed with blue quality intellect gems they would have 123 (including 11 with talent) intellect, 1845 mana, 18 spell power (with talents), 1.5% to crit and 23 extra mp5 from a replenishment buff.
If you gem all your sockets with blue quality royal twilight opal then you have 63 sp and 21 mp5 (but you don’t rely on the buff). Less mp5, less mana, less crit, but 45 more spell power. If you socket all 6 mp5 gems, then you would get 42 mp5. I know it’s not realistic to think that you would socket all one way or another – but just as an idea.
Don’t forget that shamans also have Water Shield and mana stream to that will boost mp5 another 185 at least. That doesn’t even count talent points and glyphs that would increase it even more. On top of this, our gear has a great deal of MP5 on it already. Don’t waste a gem slot on 3 or 6 mp5. Use the slot to increase your intellect and let your raid make up do its job. Let the Ret Pallies, Hunters, and Shadow Priests handle your mana regen while you concentrate on healing.
As you gear up you are going to notice that you are rarely going to run out of mana. If this is the case, you can start replacing some of your intellect gems for haste or crit or more SP, depending on how you like to play. Chain heal healers will most likely enjoy haste, while Lesser Healing Wave and Healing Wave healers will most likely enjoy crit.
If you are guaranteed to have the replenishment buff – socketing for intellect is the smartest solution.
On the other hand, if you don’t have the buff – your larger mana pool will likely not make up for the mp5 and SP you will miss.
