About mana...Follow

I have a question about pure damage output versus viability.

I am level 45 and currently a demon-sacriface/afflic build where I sacc my felhunter for the 3% of mana every 4 seconds bonus. My cast cycle is CoA, Corr, Immo, DL, then spam SB or DL. This build has been really fun and easy. I dont have to drink or life tap often, load up on spell dmg gear without fearing mana lost, and can just spam away through 4< mobs and I am usually top DPS cept for pesky mages. Now, I know I can just life tap the mana back, but I am just in love with the passive regen.

At 48, I want to respec to demo/destruc for some PVP fun. I have decent gear from instances. My question is should I go with the demo-sacc for the 3% mana regen or should I just go pure destro. I know that destro build requires a lot of mana and good gear.

My demo sac/destro build:

This is probably pretty cookie-cutter. I will fill Imprv Corr then the rest of the destro tree after getting bored with PVP. This is my first lock and my first venture into destro. Any thoughts and comments would be appreciated.

Thankx,
