Pretty simple: Which one do you think is better in the following scenario:
http://www.wowhead.com/?item=45165 Worldcarver reduces crit to 32% and caps expertise.
http://www.wowhead.com/?item=40384 Betrayer of Humanity boosts the crit upto 35% unbuffed but leaves expertise at 16.
So basically 10 Expertise vs 3% Crit. What will you choose?
Edit: Might I add, atleast 90 attackpower unbuffed and the Str on the carver gains bonus from kings.
Rawr definately says Worldcarver, but I want some live opinions.
