constant buffing of players that already was balanced

i don't know much about the game i only played for 2 years most NA and EU but i do know this is really upsetting what you guys keep doing you keep buffing champions unfairly especially that new buffed mordekaiser now you're telling me mordekaiser alone can perform all 5 roles in the game he was a good top he was a great mid he can support he could jg now he adc!?!?! what's going on the the balance you guys might as well make everyone able to perform that role why not just put ashe as a tank why not let vayne go full ap cause that's what you guys did to mordekaiser every game mordekaiser can ult every few seconds he can take control of the dragon why not just let him take control of the baron while you're at it psssh this game went from being cool and balanced to this crap i honestly don't even know what you guys are thinking but i can honestly say you're not using your brains to do it
