I always felt Singed needed a shield bash.
Singed has this massive shield, but it doesn't really do much other than look awesome. I had an idea that Singed should have a shield bash on his first auto attack when an opponent steps in goo. I wanted it to have a .5 second root so he has another way to pop Banshees's.
After reading this thread:
I thought a good idea instead would be to give Singed's next AA after successfully snaring an opponent a shield bash, with a minor knockback(maybe 1/4 the distance of fling) and a little damage boost on the attack.
It would be amazing for either screwing over one champ, or pushing a really strong enemy out of a fight so your team can jump on the person who was just flung.
It would really raise the skill cap on good Singed play vs bad Singed play.
