Make Zeke's Harbinger more flashy
I've been starting to build Zeke's more when playing support for a while and while I find the item really nice and interesting, I'm a bit disappointed by the lack of flashy things when it activates. This is too bad since it's quite a dangerous effect and can be lost in the chaos of battle. This would make it easier for carries who might not be paying attention in SoloQ to react to it as well as introducing a bit more counter play (although of a very basic kind).
In addition to the yellow glow, it could have a thunderous ramp up when it starts and throw some particles around. It doesn't have to last the whole time but a sort of "gong" to signal it would help a lot in making it work with (and when playing against it) for people who might not expect it.
