Hey there, stumbled over this website and thought it looked promising, sad times to find protection warrior barely/not implemented yet. (Although understandable)
If you would like a little input I'd be happy to throw in my few cents.
I'm not a super hardcore raider (anymore) but the GM, Raidleader and 'maintank' (which isnt really a thing anymore) of Furious Gaming (http://www.wowprogress.com/guild/eu/blades-edge/Furious+Gaming) generally we clear while current.

Seems fine to me, if self healing includes shields (Also overhealing might be interesting then)
Sword and Board isn't an event in combat log anymore I believe (which makes this kinda crap to check if you're doing it wrong or not)
Shield Slam usage should be checked though, should never not be on cooldown effectively :). (If specced for heavy rep Shield Block should ideally be up).
Not rage capped seems right.
If specced into Ultimatum & Vengeance you ideally never cast an Ignore Pain for less than Max rage (39 I believe is the max when you're under Vengeance). Naturally Ultimatum procs should never be wasted.
Cast count, not wasting a global, this is something I for example could improve on, I sometimes sit there hitting Shield Slam for a full global when I should fill this with a devestate or something else.
For defense you should also not hit Focused Rage when you're 'rage' starved and still tanking (another hard thing to check from logs I imagen)
