War's a bit squishy?

[Megguido]

I would suggest to not macro your defensive skills. You want to activate those at a precise moment, you need it to be as responsive as possible. Macros aren't responsive. Also sometimes you want to use Raw Intuition without Awareness (to boost Shake it Off shield for example), or just to mitigate a guaranteed critical hit (like Shinryu ex' or Halicarnassus' tankbuster). You don't have that much buttons to deal with as a warrior, I'm sure you can do great with Raw Int and Awareness on a separate button

On the WAR vs DRK topic, a common mistake is thinking "more cooldown" = "better". For example, WAR has a 20% HP boost on a 120s cooldown, DRK has a 20% HP shield on a 15s cooldown. Also a warrior has to sacrifice its own damage output to use on-demand mitigation (Inner Beast), whereas PLD and DRK can use Sheltron or The Blackest Night without any drawback. What makes WAR's defensive kit OP isn't its 3782 defensive abilities, it's Holmgang.

Also, while pulling several mobs in dungeons, you want to cycle through all your cooldowns, starting with the most powerful. For example, start with Vengence, then Rampart, then Awareness + Raw Int, then Thrill + Convalescence. Rampart and Vengence stack together, but in a multiplicative way (it's not 20%+30% = 50%, it is 20%*30% = 44% damage reduction).

Megguido nailed it here. Proper cooldown cycling is incredibly important for large pulls in SB dungeons. The layout and order he listed are exactly what I use as well. And considering how short all the CD's are, you will just about always have some of them up for the next pull. No 3 minute CD's here! (F-YOU Sentinel)
