Why is everyone looking for 100% equality?

On the boards I've noticed that everyone is looking for everyone role to be equal to each other.

Heres what I personally think. I don't want Ranged Attack Damage Carries bursting anyone down instantly.

I don't want mages to have as much DPS as a Attack Damage Carry.

I don't want Assassins to have as much CC as Tanks.

I don't want supports to have as much CC and damage as Bruisers.

I personally think that every role should be able to keep its identity. Mid lane- Burst/Wave Clear Bot AD- Constant damage Support- either CC + tank / CC + peel Top Lane- Bruiser/ CC/ Hyper Carry Jungle- Whatever the hell Riot decides jungle wants to be this season.

I might be too closed minded to this Whole Lets Take AD everywhere.

But seriously, guys accept that not everything in League of Legends is going to be completely equal.
