I am having the same problem on mana issue,
but this is how I deal with it, have to pull out all the tricks
I speced into this

- even though evangelism helps cut mana usage, but in the process you use more mana to get that stack up to 5, so until I get more mana regen
I'll just cut down evangelism
- eat spirit food, and drink spirit elixir, helps a ton
- Power Infusion yourself
- Inner focus and use Greater Heal, will most likely crit and buy you more time to heal
- Barrier(glyped) + Pain Sup in tight situation (if you can, PI yourself, Inner focus and GH galore)
- Hymm of Hope before using your shadowfiend to get more mana back
- I know mana potion is sky rocket high price right now but 10K mana is not something to look over, use it if you can.
- run normal to gear yourself up if you can, running heroics in green is kinda painful
finally you will in the end feel better when you have more gears.
hope it helps
