And you are wrong it takes a daze or a stun to knockup a person.
And summoners are only good at pvp because of the air combo. If you remove the aircombo summoner is as good as useless in pvp. And let me tell you how hard it actually is to aircombo someone, i mean we have to stun or daze you first before we launch you into the air so you have a full second there to tab out before we hit v. There is a super super low chance that v will crit and we can v a second time but that chance is very low and doesnt even happen everyday. (Btw we cant launch you with a kd like you say). And summoner actually has only 1 resistance skill and thats not many like you say. True friend is a 5 sec resist and beckon and ss are 1 second iframes. Thats it. Those are all the iframes we have, and if you hit into our counter then you only have yourself to blame for spamming
