okay I can understand the changes to HS, I mean being able to increase block by 30% basically all the time would be pretty imba, esspecially as we're able to block ~45% of all damage (30% base + 16(?)% from mastery)
but what about shield block?
http://cata.wowhead.com/spell=2565 100% block chance for 10sec with a 1min (40sec talented) CD? add in Critical Block (30ish% chance to block 60% instead of 30) and.... can you really see anyone whose not a warrior tank getting the MT slot? or has this been confirmed for a change?
