Ekko's W is just a much better Bard Ult?

Ofc they both have their weaknesses and strengths and they are different in what they do... But Ekko's W seems a lot more practical and a lot better for teamfights.

For those who don't know what it is, Ekko throws down a bard ult that slows down enemies who walk inside of it, and if Ekko himself walks into it it stuns everyone in it, WHILE giving Ekko a shield. SEEMS LIKE A PRETTY CHILL ABILITY. Meanwhile Bard is the mascot of trolling.

idk i feel like ekko is going to be a really OP champ on release, unlike Bard
