Iron Fist ult should extend on successful block

So I’ve been thinking of a way to buff iron fist ult without just giving it more damage and being boring and I think I’ve come up with it. What if when he successfully blocks It adds a few seconds to his ult timer? Ik it would take some adjusting to get right but it would be so cool and promote high skill ceiling as the best players would be effectively in ult for double maybe even triple the length.

I feel like he’s in a pretty bad spot imo but think just a damage increase could break him so I’ve been thinking of alternate buffs so lmk what you think
