Kinda not true. This combo has one specific 2h-hammer skill (whirlwind), one standard aoe skill which requires 2h-hammer (rather new skill of warrior, opposite of moon cleave but for 2h-hammer, ID: 1492578), standard warrior skill zyklon, standard warrior ISS Crecent Moon Cleave and ofc champion skill shock strike (with a 2 sec CD).
I think your request is kinda against the idea why they changed Moon Cleave and added a second skill for different weapon types. This class combo has good single target dps, aoe dmg is ok, but buffing it would definetly making it too strong and you can still use a lot of shock strike.
