Hey guys, I've been in a bunch of groups recently that have been claiming that the defense cap for raids is 545. I was always told and guides have said that the defense cap for raids is 540. So, which one is it?
The groups you are hearing are wrong. While it is not wrong to stack more defense than the "Crit-Proof" caps (535/540) it is generally considered less than optimal.
So having 555 doesn't make you wrong. It just means that some of that itemization could probably be better spent on other tanking stats.
