@Riot How About an Anti-Shield Ability?
I've had this idea for a while now but why not give a champion, preferably a support, an anti- or inverse-shield ability? As the name implies this ability would do the opposite of a shield and do damage, looking something like this:
'Anti-shield'- After a delay, Caster places a shield on an enemy champion that absorbs healing and shielding affects and does bonus damage at the end of the duration based on heals and shields supposed to be received + Caster’s AP.
Ideally it would be a direct counter annoyances like 
and 
who spam healing without forethought or for dealing with champions that simply refuse to die 
and
.
Of course the ability would have its downsides like:
- A cooldown similar to Yasuo's WindWall or even just be made an ultimate ability itself.
- Being able to target only one champion.
- Short casting range.
- etc.
Thematically I think it would work best on a witch doctor or hex, character.
