If you didn't know, Grohk can't use Shock Pulse [RMB] when he's reloading.
This is a huge weakness especially for the Spirit's Domain talent as you tend to reload more to stop teammates dying.
All healers can use [RMB] during reload (except Grover ofc - doesn't reload). Furia, Seris, Mal'damba...even Pip (as Explosive Flask [RMB] deals dmg like Grohk and is CC).
Lightning Rod, one of the top sustain cards for Grohk takes a hit as well.
Lightning Rod: Hitting a champion with Shock Pulse heals you for {30|30}.
It has more "healing per second" than Healing Totem [Q] so it's useful if flanks try to kill Grohk.
In short, please fix this...
