"Hammers focus on massive impact and long-duration crowd control. While Maces are often more versatile, Hammers excel at locking down specific targets for extremely long periods or providing the "hard" engage that decides a fight in seconds. The Great Hammer and Tombhammer are legendary in the Mists and small-scale PvP."
The "Tackle" (Great Hammer E) can travel through walls and obstacles; use this for surprise engages.
Use Grasp of the Undead (Tombhammer E) to pull kiting enemies back into your team.
Pair your stuns with your team's burst for guaranteed kills.
Be careful of being kited after you use your mobility E.
These are the top performing builds pulled directly from recent PvP combat data.
To provide a wind wall for your team after you engage.
To reveal and debuff targets for your team.
To reset your Q ability for more sustained CC.
