at what point does the amount of sp that you have become inconsequential it seems to me that i have enough sp to do whatever i need but my mana regen seems low i wonder if maybe switching out one of my trinkets that have 106 and 111 sp on them to one i have that has i believe +84 spirit i does make my mana regen higher but do you think the -111 sp i will be having is gong to make my effictive heals less....well just less idk maybe i should just change my enchants to spirit instead of sp let me know what you think

MP5 may become more interesting that spirit with the mana regen change in the 3.1 patch (where the out of fight mana regen (the one done via spirit) is nerfed by about 40% (the last time I have checked). So you will probably need to rethink all your equipements, enchantements and talents to optimise your mana regen (and play near of a class with the replenish effect).

Innervate is getting a big nerf in 3.1 so yeah, MP5 might be the better deal.
