Hyperion Counter-Play
This is really more about countering Power Gain, but it applies mostly to the higher 5* duped Hyperions because the Power Gain is so extreme.
Is there any other counter play besides trying to bait SP1/SP2 before he hits SP3? I don't have many champs with Power Block or Power Drain, and those that I do have can't apply it reliably or fast enough. The known bugs with dashing and commands also factor into my frustration with this.
It seems like this is more luck than skill, which I find very annoying. Sometimes, the AI will use specials a lot. Other times, the AI doesn't seem to want to use them at all, and then I'm destroyed by an L3.
