Questions regarding summoner

With summoner coming in around 2 months' time, I wanted to ask the players who have had experience with the class playing in RU/KR, what do you guys think about the class? How its is survivability, movement animation, and most importantly DMG compared to other classes. Also if possible I was wondering if there would a tier list of DMG with summoner in it to showcase the difference between classes.

​

Thanks in advance!
