Banshees on long range mages will be a problem at some point
The counterplay to these long range mages is supposed to be their immobility and being prone to being engaged on. Banshees removes that weakness because these champions typically will be difficult to even pop the shield off in the first place. These champions already can be fairly difficult to engage on due to their long range and giving them the banshees shield will make that a bit more problematic. i like that banshees got a niche pick-up option but I'm not sure this is the correct way to go about it.
or
. It would be nice if it combed with
to do more noticeable anti-hp-stacking now that we've got champs hitting over 10k hp (or so I hear)
