A tank I play with has really odd itemization choices.. always has, really. He has all Karazhan and most of the TK/SSC drops, but his stats are a little different than mine and most other tanks with equivalent gear. He values dodge and block rating more than most other stats and sees block value as useless except when "dpsing" (he puts on all block value tanking gear when farming or prot dpsing). When I asked why he was using that really bad block rating trinket (he has all the good trinkets available, so it wasn't a no-drop issue), and told him that block rating was sort of a useless stat to stack (he prioritizes it, along with dodge and parry, as THE tanking stats), he responded with: "Hardly useless. I stack so much block so I can be passively immune to crushing blows without shield block up."
Here's what confuses me. With all of the gear obtainable in BT/Hyjal, you should eventually be able to achieve being passively immune, but what's the point in actually trying for it, especially this early on WITHOUT BT/Hyjal gear? This guy has no hit rating and block value so his TPS is a little lower for the content we're doing, his HP is low considering he's the other MT, and instead of prioritizing those stats, he's sacrificing them.. in an attempt to be passively immune? Is it really worth it? Shield block isn't difficult to keep up, and you can switch out gear for fast-hitting mobs.
I just don't really see the logic in this. Maybe I'm wrong, but considering this guy MTs with me, I'd like for us to be on the same page here. Help?
