This macro for paladin tanks it works pretty good with right gear and spec. It works for me very well when I tank once in a while. Basically this brainless macro has a small sequence with modifier for Avenger’s Shield and pops cooldowns whenever available.

/cast Consecration

Macro Explanation:
UPDATED July 8, 2011: Revised for Patch 4.2 and also added trinkets.
UPDATED July 23, 2011: Added Holy Shield instead of 1 trinket for more avoidance in less time (Thanks to Baine for the idea).
