Balance isnt really hard please make an effort to create some in your game.

I am not suggesting perfect unified balance among all champions, i am asking for some basic balance, as in if i build dmg, i do dmg, if i build defense i get tanky. I am not sure why some champs like lets say Ad fizz gets to build 2 dmg items and literally out dmg a champion like an adc who builds 5 dmg items.

This is not hard to balance at all, you essentially provide each skill with an equitable base dmg rate and then a ratio. Bazaaam now if I build dmg, and you build 60% defense i do more dmg than you... but because you built 60% defense it takes me longer to kill you....and in the end we will come down to the last shot give or take a crit. This is vastly different from the current game balance where a champ like fizz misses his ult and still blows me up with 2 dmg items before i can take him to 1/2 hp even though i have a defensive item (randiuns) and the rest offense, while he only has 2 AD items ZERO armour pen and the rest a mix of armour and MR items.

again nothing complicated, just asking that champ selection doesnt determine the outcome regardless of how we play when we both amass the same gold.
