How Important is hit

[Thadeaus]

I know the hit cap but what im woundering is how important is hit for a tank? I was a believer that a tank should have his hit maxxed out but a lot of the other tanks I talk to shay you dont need to have it maxxed.
I want down to 177 hit and I do find a bit of a difference in things, such as sometimes my Taunt is resisted or something like that.
As for threat even at 177 hit im fine generating threat, on 25 mans i average 7.5-9k threat with spikes up over 10k.
Sould i be gemming more for hit or not?

Hit is still important. Just not at the loss of survivability.

It really sucks to see your timer for Thunderclap at 2 seconds, use a CD on Thunderclap, and watch it miss. Getting your debuffs on at all times is why I am attempting (not reached yet) to hit the cap.
