What does riot do with these champions?

There are a few champions that I feel like riot kinda makes and forgets. Champions like Galio, Yorick, Shaco, and Poppy. Not only are these champions not in meta almost ever, in Galio's case, he is never played in lower elo, and he is not played that much in higher elo even though his kit is pretty ridiculous.

His kit is a very unique kit but a useful one when used right. His Q does ridiculous damage and has a 0.6 ap ratio and a base damage of 80/135/190/245/300. That is a ridiculous level one damage one of the highest for a lvl 1 spell and this spell reduces there movement speed. His W is one of the problems of his kit. In the laning phase it is pretty useful because it will heal you for whatever damage you take. But it doesn't ignore the damage. If the damage is high enough it will hurt you more than heal you that's why it is useless in team fights because you are taking so much damage. His E Is a great utility spell, it does decent AoE damage as well. It has a 0.5 ap ratio, and a base damage of 60/105/150/195/240. But the most useful part is the movement speed increase of 20/28/36/44/52%. If you combo that with your Q it is a great engage spell. His R is what makes him truly unique. It taunts anybody who is in the range and who walks into the spell cast, then explodes dealing 220/330/440 base damage with a 0.6 ap ratio. This if used right can cause a lot of winning team fights. It will start a fight for any other champions who can engage. And if the other team is smart they will burn whatever anti CC thing they have such as . This will then give your team a chance to use more CC on the team.

All I want to discuss is why is Galio not played!? LEAVE YOUR COMMENTS BELOW AND THANKS FOR READING!
