i just upgrade my Toc258 http://www.wowhead.com/?item=47415 with
Gear score is same.
But from tier 10.25 chest we get
37 Sta - main stats for tank
46 Str - main stats for threat
1243 Armor - awsome at this level
77 Parry (1.57%) - v good for ICC where you get dodge reduction
and we lose:
102 Defense (20.74) - we are overcapped at defence anyway so crap
9 Dodge (0.23%) - almost nothing and in icc realy nothing
78 Expertise (9.52) - some good stat but not main, better parry anyway
1 Sockets - still 1 socket with 30 stamina dont even is over 37 base stats from t10.25 chest.
So, with this all usefull stats, i dont get it how both of the chest can have same level.
