Zeke's Harbinger's active is so awkward to use and see being used effectivly

And I think the only reason for that is that the active gives almost no indication it has been popped, sick of seeing it being wasted on champions who decide to run away when it's active Can we please have the active make both champions bigger for it's duration, since a lot of things are getting the "increase size passive" on them to make people know they are more powerful, so why not do it with the item what grants 50% critrate and 20% increased AP
