Request for secondary action requirement for Paladin Ground Slam

#1

I would like to request that there be a secondary action requirement in order to trigger Ground Slam, aside from just touching hammer to the ground. Perhaps holding the trigger button down before said slam.

I’m asking because when I’m running around, I have to hold my arm up in the air to prevent my hammer from making landfall, because it keeps accidentally triggering ground slam and using up my orbs.

Thanks for your consideration
