Did you perhaps change realms? Please fix your profile so it points to a relevant lvl 90 character or preferably your main.
All of these are tooltip corrections. No changes are being made. RB hasn't required you to be enraged since last expansion, and the damage tooltips on Execute and IV were just wrong for Arms.
I originally had thought they might be changing the proc mechanic for RB to be similar to that of MS/OP, but it makes sense it's just a tooltip correction, as RB's timer is longer than the enrage buff.
