Balancing ADCs, Supports and Assassins

So we all know that the adc's are too strong right now, everyone is complaining about them (or shield supports).

My idea of balancing this is to simply revert the assassin reworks.

The thing is that pre-rework assassins didn't have their damage delayed, but if they were to be with their old kits now, it wouldn't be as simple as before, because of all the shielding supports (for teamfigting; other supports too) and items that have been changed since the reworks, where it's preety much impossible to one-shot someone who has Deaths Dance. (I know that not many ADC's buy DD but it's worth mentioning) ADC's would have no excuses for being one-shot since GA is now an AD item, which is also going to be built from an item that is basiclly a one time zonya.

As I see it, reverting the assassin reworks is a win-win balancing change because as I already mentioned, ADC's don't really have an excuse for being one-shot, not even from stealth. It would balance the game by bringing back that Class-Counters-Another-Class while not being un-outplayable and would give the assassin players those kit's that made them love that champion in the first place.

Of course that would also require assassin item balancing, because no one would like to play against this new duskblade on Old Rengar or any other AD Assassin.

Thanks for reading and please comment what you think about this. Have a nice day/night.
