[2021] Can we talk about Viego's design? (Not a power rant)

I just feel like after the amazing champ sets we got, Viego is just so... Meh. JaDe GoLeMs, I know.

Feels like the design team really dropped the ball here, and not to be that guy but I think they should rescind the trailer and try again.

Personally, I would've had Viego (on the assumption that he's exoensivs (5 mana +)) temporarily steal the strongest enemy champion or follower the first time he gains the attack token each round. Till end of turn, and it prioritizes champs so like even if the selection is literally Braum and a stacked Heart of the Fluft, he'd snatch Braum.
Level up would be to see Stolen enemies deal X damage or die X times, and his lvld card would summon mists that take damage and removal effects in place of viego (while keeping the stealing ofc).

That feels like an interesting design on power par with what we got in this latest mini set thing.
