i think the ability for the devs to entirely ghost the entire community is a bit on the stronger side but instead of nerfing the effect maybe you could adjust it so it has a longer cooldown, that way instead of just stacking the buff so that when it expires they can recast it, they're at least forced to interact with the community during a small timeframe, perhaps once a month (or week but that might be asking for too much).
imho the current state of it makes it very non interactable which is pretty unfair for player-centric builds
also maybe controversial but the ghosting ability shouldn't also stall patch timers
