Shyvana Gameplay Idea

So, not really sure where to put this, first time posting on here. So hi. But I had an idea for Shyvana, since she is one of my favorite champions, but I feel she is a little lacking. I think that shyvana should have a heavier push on being a tank, given that her passive is just strict armor and magic resistance. However, currently with her kit she just uses that to bully in lane, get the advantage, and get damage items. I think that marked targets with her e shouldn't take extra percent damage based on their maximum health. I think it should be reworked so that way, when you use your q on marked targets, it either stuns or slows them. I know some people will argue that that will make her way to powerful in lane, even removing the percent damage, and I can see that. Shyvana does have high base damage, so if this were to come into effect I think her base ad might need to be lowered. and possibly the base, or scaling damages of her abilities. With all of this I think it would lead to Shyvana getting played more, and on top of that, being played as a tank with a utility option that could really make an impact on a team. I think this would be an amazing change to Shyvana, and I'd love to see it so I just wanted to put it on here somewhere :D
