Full screen or half screen it doesn't matter. For me, it's how they execute it or the timing (skills). The game have delay animation to your screen compare to the player screen.
As you can see to my previous post Camera1 and Camera2, the archer screen is precise and gradual/normal however when you see to naga screen it's not the same at all.
Now, CE is different thing. No more animation, the movement and the skills is fast compare to my video.
Anyway, I'm familiarity with banar not archers. If my post is unreliable as you think it is, feel free to correct it. I know lots of players here are expert using archers. Please feel free to post your opinions.
