They say "just build QSS against veigar" this is false because veigar can just q+ulti and your dead without even landing his stun.
build qqs vs veigar, use it and flash , veigar just lost a chance to kill you
build qqs vs zed ,he ults you you remove his ult but he still mashes you, you flash away but he uses w and still hits you,you cc or use your mobility and he flashes after you just to still hit you(or he dodges a skillshot), you have loads of useless magic resist and even if you manage to fight him he can just pop back out
so you just wasted some gold while zed gets youmus and infinity to stop relying on ult for damage
veigar has less counterplay in his kit than zed
zed has less counterplay in his gameplay than veigar
riot gives counterplay to veigars kit meaning that he will get rekt in gameplay, most of his usefullnes was from oneshotting carries, this wont happen without a stun
also next example that gets me mad
lee sin/ jarwan get good base stats, good scalings,good cc,good mobility and they arent the only examples of that
meanwhile darius and mordekaiser just deal damage, and not some insane damage, their damage is good but a well build bruiser can either win a trade or survive long enough to escape from them
first thing, the stats have to be ballanced to prevent cases where you just cant fight anyone because you will get melted once you get in their range, thats why morde and darius dont get to be the masters of damage
consider this and notice that some champions get owerloaded with usefull stuff on top of good stats while some just deal damage and cant even get a high amount of it cause it causes toxicity
and now they update mordekaiser and still dont hink about giving him cc while completly wrecking his damage (old morde built like a tank deals better damage than new morde with the same build, and riot will enforce the tank build on him)
