I'll have to agree. The actual problem with Sivir's ult is that she will be in a lane with a Surelya's using champion, since most, if not all, of the supports will get it. Any time she wants to use her ult, her support can use Shurelya's for exactly the same effect, and while at a diminished value, most of the time the movespeed from the item's active is good enough. Chaining with Shurelya's for running away or initiating is another thing, which while good, I feel is... mediocre. Movespeed is good, but in LoL gapclosers are common enough (flash included) that just jumping over that wall might make the chase useless. Also, it is boring as heck, since the only thing you do is press R and run.

Do notice that Riot feel as if she will be undertuned on release, so they might end up taking a look at her ult's active, which looks as the only lacklustre part of her kit. Your suggestion sounds good, but I would actually look into doing something like giving her passive in an AoE to her teammates, so that when she hits something, everyone gets sped up and it refreshes when she gets another hit. I think that ties nicely with the AoE she has, so that the whole team will be fast as hell during teamfights, and the enemy's backline will be pressured by the bruisers and assassins. It might even make nongapcloser melee champions a tad more viable in a teamcomp with Sivir.

TLDR: R->When Sivir activates her passive during the next 5/6.5/8 seconds, the speed buff is applied in an AoE to her teammates, and refreshes the duration on subsequent activations.
