Nice face and tattoo selection.
Basically, it works like this:
Pal and War have the same static EHP. With 15% War healing in healing intense scenarios, Pal have 8.7% more EHP. At 0% healing, Pal have 25% more EHP. Yes, you could likely orient your entire raid around having a War tank something or, you could bring a Pal, and have a lot more flexibility or room to optimize. Pal have 2 (or arguably 3) tanking cooldowns that blow away everything a War has. Lining up an big IB is good and takes multiple cooldowns. A Pal clicks one CD and they do everything IB does only better and for an extended period of time and execute faster.
Pal are not invincible. They are not indestructible tanking deities who laugh as they are tickled by raid bosses. They are, however, undisputedly better at tanking than Warriors.
