Mark my words...
Riot: due to the ability to lock out a teammate in a critical teamfight is too strong or lacks meaningful counterplay we are gonna keep the ult duration and just make it scale by rank.
Me: in other words the Camille treatment in her ult timer increases per rank. pro play is the reason we cant have nice things. such a fun looking ultimate is gonna be gutted.
also after all 7 secs in ganking during lane time is very powerful also.
