Riot's Balance stystem Season 8 [COMPLAINING]

Vel'koz,Aurelion sol,Azir,Xerath are SOME of the champions that are mostly not played by players because they have some really har skillshots and they have a ton of counters.Most of them are assasins. What I want to say that many champions are forgotten because they are weak against most of many others. I will tell you an example:I was playing Vel'koz in MIDLAN,I had actually a very good score of 15/2 but they eney team had a Yasuo JUNGLE FREAKING JUNGLE with a score of 0/4 and only 109 cs at 25 minutes. When we started our fight he caught up with me WAYYYYY TOO EASY but and I tried to defend myself throwing my SLOW and defficult to hit skillshots.In the end he simply blocked them all with his W.Then I got pretty much DESTROYED. He attacked me to death and as I was waiting for my LONG cdr to reset.With that I want to say most of the mages,NOT ASSASIN-MAGESjust mages,are very vulnerable to all of the assasins.And with that champions like vel or aurelion get forgotten.And all of this because of the balance system.The only thing I ask is to increase the base armor and movement speed.JUSt this.

Thank you if you red all of this :)
