Someone please explain morale

[Lemuria]

So... does morale only affect the one item that has it or does it work across all gear? I ask because there's a lot of Morale gear out there, and a full set would put a player at well over ilvl 180 if it worked on the base stat alone.

On the other hand, having mid-tier morale equips makes PVE gear more appealing due to its higher ilvl.

A fully detailed explanation about how both Morale and ilevelsync work can be found here along with several BiS sets for all the classes.

Quick and dirty:
Morale
When in PvP areas gear with the Morale secondary stat has its ilevel increased by the morale bonus. Secondary stats are increased by the difference between the stat cap of the item's original ilevel and its new effective ilevel.

Ilevelsync
When you are in an area under the effect of ilevelsync the stats of any gear with an ilevel above that ilevel are decreased to the stat cap of the synced ilevel. If a stat is less than the cap it is unaffected.
