Yes it was ever so clear to see the 'choppiness' of your tiny devices on the sideways screen. All I could make out was the time it took for you to realize skills were cooled down and use them. I can't believe you would call someone ignorant while making a generalization based upon yourself and only yourself. So it runs choppy on your device, luckily for you they're making optimizations. Regardless of your situation, it runs perfectly on mine.
All you really need to see is the mordris animations. It's clear the iphone 5s was running a bit choppy even with nerfed setting.
Don't believe for a minute it runs the same on your iphone 5s as an iPad air during raids. Given the others it dosent run smoothly on during those times I'm guessing you just don't know any better. It's more likely than somehow you have a magically different device than everyone else.
There are only a very few people saying 5s 'runs smoothly on the highest settings' during raids and an overwhelming amount saying otherwise.
