Shadow: mana management in BGs
* Dispersion is a defensive cooldown, so it's a bad idea to use it merely to regain mana.
* Replenishment is a joke, and with t10 4p mind blast is worse than mind flay. Plus if you are in a big group you will have Replenishment on you all the time anyway.
* Shadowfiend is unreliable: enemies die, move around, peel it... and the glyph is bad, 5% might as well be nothing.
* Hymn of Hope is 12% and because of its cooldown it cannot be considered.
* Darkglow is useless: 400 mana on a 45 sec cooldown.
So... go with spirit gear? In that case, what is the minimum spirit one should have?
