I do a two-box team as a lock and priest. They are at 69 now. (70 soonish)..

Just to give you an idea of my setup (Pick and choose)...

I run the warlock as my main.. Why? Just happens to be that way. Healing is way too easy with clique and grid. My priest is currently shadow (And plan to stay that way). I dont broadcast keys. I use two layers on an nostromo N52 (Using the D-Pad to momentary toggle different layers).. Normal controls the lock, shift green state controls the priest.


Macros:
A few macros that I use:
*Note: The healing macros target like this.
If my warlock is targeting a friendly, heal that.
If my warlock is targeting a enemy, heal enemy's target.
