Mechanically hard debuff support champion

Unpopular opinion: People don't like to play support because there isn't really any form of recognition that you'll get if you make an awesome play as support. In other roles you'll see how good you're doing through your KDA score, top laners can brag about their 12/0/5. People who play mechanically hard champions can actually brag about their plays, if you make an awesome combo with lee sin, Azir, Yasuo, etc., everyone is going to lose their minds in chat, but as a support, if you become the reason why your ADC was able to get a kill, instead of "gj supp" your adc will probably type "ez clap".

So Rito! I have a suggestion! why not make a mechanically hard support champion!? And to make it even more unique, instead of giving buffs to team mates, it could instead give de buffs to the enemy.

Shield disable, unable to use a dash or mobility spell, lower tenacity(was it called brittle? idk), lower attack speed, increase cd, lower magic resist or armor, etc.
