Just Someone explain to me What is the counterplay to mages damage ?

Whats the counterplay to mages damage ? we reached a point rightnow that mage can just burst half ur health with 1 basic spell thats probably on low cooldown ... My probleme is That it doesnt matter if u build resistance ? one, is 2650 item That gives u 70 ap and 40 % magic penetration, Still exist in game , ... Whats is the point if u just gona build 1 mr item and its been negatited by less cheaper item ? and because for Some fuking reason, mages item give so much fuking dmg While they have so much good defensive option , best active in game, this item on its own is busted with infinit man and increase ap base on mana and lets not even talk about that broken shield, her stat are too good, , That makes playing tank into mage nightmare ... etc Two, Why is most of champ base mr and scaling in game is so low When there's more ability power in game then ad Even tho, armor is high on base and there item are in ok spot, u dont belive me ? Test playing vs full ad team, High chance u'll win by late game But face full mages team ? Doesnt matter, even if u build mr ... u'll survive 1 rotation That is probably on low cooldown but u wont survive next rotation ... But u'll probably bring the argument of " But ad champ have high dmg auto attack" While i do agree This's argument is good, Just ask ur self ? Who would u win 1000 ap syndra ? 1000 ap with minimum of 52 magic pene, Oh yea with 1000 ap Vs 1000 ad Adc, 1000 ap vs 1000 ... do the math and u'll find out Its uncomparable honesly Three and this an other thing that puss me off about mages, Why they have to be strong at all stage ? Lets take , Lane bully, midgame powerhouse, late game she need 1 button to 1 shoot someone and its point and click ... Like ? and this exmpl applie to high majority of mages with few exception, in what world and are weak early game ? its honesly biggest lie has been told by riot, Just like saying has weak laning phase... Riot exuse to all this bullshitt is that if mages were brought downbet, Then adc will start killing them if they dont hit basic spell That can does half ur health... which some fking dumb bc ... This's just an exuse for bad players, so u miss 3 seconde combo that can kill an adc and u fkup now. wait ... Let me just then and try my seconde chance of hitting my buttons That will health bar my oppunnit and if u are too lazy honesly, Just play point click vurst champ ... Who the fck need to be skillfull player anyway ? its 2020 Now this post would probably be downvoted bc god forbed if anyone talk about mages Even tho half of community complaning about base dmg being too high When realisitcly and if they open there eyes, Mages are the highest source of burst dmg in game ? i wana bring 1 more fact before ending this post That the number 1 anti mages in game suck rightnow, Only reason is good bc that champ has an assasin base dmg.
