Djin Command Skill and Scepter Bug

After several tests, I found that when you set Djin's command skill in another weapon set, there will be a small delay if your scepter has "+All Minion Skill Level" modifier on it. If there is no such a mod, the command skill will activate right away. This is a huge nerf to Djin builds if we are stuck to just one weapon set. Can you address this issue as soon as possible?

I second this.
Also if I use other skills during the delay, the Djinn's skill will never activate.

I also found out that on the same setup (weapon swap with +#All Minion Skill Level) Djinn's channeling skills like "Kelari's Judgment" are bugged, sometimes my character just freezes in the command animation or the skill doesn't go on cooldown and it is unusable until I weapon swap or I use other commands skills.

I would like to add that this bug doesn't happen with just scepters. Even foci have the same issue if they have "+# to all minion skills" mod. I assume any gear that modifies the level of minions will cause the issue.
