Best approach for arena?

[Ualaa]

I've found a pair of players, who are decent in 2's.
They're willing to run 25 games of 3's, with my toons for three weeks.
I'm paying them per win.

That will be three weeks of five wins per toon.
With the Conquest weapons, that should make things a bit easier.
I've implemented everything mentioned here, except the Engineering, into my set up.
I will be adding the Engineering at some point.

Currently the DK's have Alchemy + Nothing.
So they'll each get Engineering.

The Pally has Alchemy + Enchanting.
There is the possibility of running heroics with this team.
But more likely, I would do it with another team.
The Enchanting is specifically to be able to disenchant.
Is there a significant disadvantage to not having Engineering on the Pally Healer?
My focus is battlegrounds, but arena would be nice for points each week.

What I have found with engineering in my experience is its over rated. I was either going to win without it or lose having it. It made very little difference. So much so that I dumped almost all my engineers and went blacksmithing with a couple of my characters, I like the extra gems. /shrug
