Repairs (frequency)

Its totally understandable that as a tank your gear gets worn down / beaten up much faster then others. But I personally think the rate at which I have to repair as a tank is slightly high. After about 3 instance (CM) runs my gear is at 20-30% durability, as compared to my bard i can maybe run 5+ without even needing to check my durability.

Im not complaining about money issues having to repair so often rather just how often I have to get to a vendor to repair. Would it make sense to scale up the durability on tank armor to have to repair less often, but also scale up the price so it costs the same?

Just a thought i had today...

Gear wear and spiritbind progress is based totally on experience gained (even at level 50, it just counts the experience you would have gained if there was a level 51). It doesn't have anything to do with taking hits, or using attacks, or anything like that (aside from death). Tank gear doesn't wear any faster than bard gear, you're probably just clearing more mobs as the tank than you are as the bard.
