Some of the abilities seem like the wrong choice/function

My biggest complaint is that Sejuani has her OLD ultimate, and it stuns everyone in a large area instead of a single target. But Poppy only hits one target. That's kinda backwards.

Pyke's should have a specified range, not just fly across the entire stage stunning everyone.

Aatrox should either do his second Q for the range, or at least knockup the target in the center of the current one.

Shen shouldn't just have half his ult animation tacked onto an imitation of his W to decrease the uptime of his ability.
