Not even during the replenishment nerf around 3.2? I had to chain darksquid/dispersion/pot to maintain my mana just on target dummies when they did that. I then spent about six months playing enhancement shaman because I found it ridiculous what shadow priests had been reduced to (rubbish DPS and not worth taking over any other replenishment build).

@theraptor

Stick to Shaman man because you haven't a clue how to play a Shadow Priest. Even without the glyph of shadow word pain, http://www.wowhead.com/spell=57192 impossible to burn your mana, I still don't even come close to running out of mana. If anything Shadow Priest should feel guilty about our mana regen abilities. I know i do, I still can't get my damn'd mana bar to move during burn phases. We need more nukes.

@Gothia

Right, because during the replenishment nerf G:SWP gave mana regen. /sarcasm

If you knew as much about shadow priests as you think you do you would know that the replenishment change affected our regen to the point where, in combination with our terrible DPS, they had to give shadow priests a mini-review. You need to stick to trolling the WoW forums if you can't tell I was referring to a specific time period where, without top end gear, it was possible to OOM as a shadow priest (particularly if you needed to do anything but DPS). The fact that they changed G:SWP to give mana regen should hit you with the clue stick that mana regen was a problem at the time.

And no Shadow priests shouldn't feel guilty about their mana regen as it is the whole concept behind the spec.
