Support Tank Potential Expanding Hitbox

As it stands supports like bard,alistar,braum all have pretty big hitboxes, which is nice to block some skill shots for your carries, but in most cases you just don't have the movement speed to actually dodge a skill shot if you are trying to, I think it would be interesting if riot made a champion that would get bigger and it's hitbox get bigger accordingly , so that when normally want to dodge skill shots you can, and when you want to block them you can.

for real though nid spears and jhin's w is 100% bull shit to dodge on these 3 champions xdddddddddd
