Does Bard bring too much utility?

My goal in any game is to feed the ADC a handful of kills which isn't difficult considering my meeps plus w allow me to win almost any early trade and a q stun is garunteed to pull out at least a heal or flash. Then once ADC can stand on there own just roam every other lane and if you catch anyone out you can snowball your entire team to victory. To sum it up early laning just land q and sustain with w and you're good. Mid game roam and snowball your entire team. And if it gets to late game seiges you can easily back door with e can steal any buff with a well timed ultimate and if it's just a pick comp your enemies have no hope because you have not one not two but three forms of CC excluding any items and you can bring your entire team through walls and boost their movement speed. Literally you cannot run I will just casually follow behind you slowing you with my meeps or stunning you against walls with q until my teammate kills you and if you think flash can save you I e right through the wall and if you try to hide under turret I will just ult it. Simply no where is safe when playing against Bard and if he can hit you with any 1 of his CC you are unlikely to survive because he will keep CC chaining you.
