@LadyAzur agreed. If you don't complete enough tasks you do run out.(Our party has a strong focus on Task Completion) However that being said, if your mages are casting Earthquakes instead of Ethereal Surges, this becomes much easier. You can also put your highest INT gear to help too. I have over 24 dailies each day to complete. Often just completing all my dailies I will buff at least 2 times per day. Often more.

Also what helps with mana regeneration is getting a "Perfect Day". Give me more of a focus to complete those dailies, so I can buff more.
