Warriors in patch 6.0.2

I just read the patch notes for 6.0.2 and arms warriors seem to have gotten the short end of the stick.
Over power and slam have been removed?
Mortal strike doesn't generate rage anymore?
It literally say warriors should use rend and whirlwind now.
Rend is a 18 second bleed, which means basically you only use it every 18 seconds.
Whirlwind is an AOE spell, and we are supposed to use it instead of Slam and overpower?
WTF were you thinking blizzard?!
