See to me this might be more of issue than the current Phantom damage they do that heals back overtime. And you’re right to mention it should be low magnitude. I can easily see something like this being more overpowered in the hands of a dominator than the way the Phantom Army currently functions.
But hey, that’s what test server is for, and if they went with this way with Dominator Phantom Army, I wouldn’t say no. 😁
