In the newest 5.2 PTR (Build 16446) we get a look at the set bonuses for the tier of the Thunder King!
Guardian 2P: Each attack you dodge while Savage Defense is active increases the healing from your next Frenzied Regeneration within 10 sec by 10%, stacking up to 10 times.
Guardian 4P: You generate X% more Rage from your attacks while Enrage is active.
The 2 piece bonus sounds pretty nice. Only time will tell if we actually attempt to save up charges for a big FR, or ignore it and treat it more like a passive healing buff.
The 4 piece obviously will massively depend on what X ends up being, but I like the sound of it so far.
As to how this will affect us with the other patch changes, we will be in a somewhat unique situation where all of our secondary stats are pretty powerful. Dodge receives a buff in that dodges under SD now give a healing buff, and mastery is being flat out buffed. Rage gen stats benefit from FR buffs and a multiplier from the 4 piece. We will also start getting to the point in our gearing where we actually have more rage than we can spend (personally I already get there sometimes), which means we can start dumping more and more itemization into dodge and mastery. So far this tier is looking mighty fine for us bears!
