The more I play with Karma the more I feel

That Sivir's ultimate ability needs to be reworked.

Maybe it's just me but Sivir's ultimate always felt lackluster to be for an ultimate ability. Yes it's a good engaging tool and it's even better if you want to quickly retreat/disengage. But for an ultimate ability it feels extremely lackluster. Also it feels EXTREMELY support_ish_ rather than ADC_ish_.

I get that Riot feels it's good to give some ADC champions utility ultimate abilities so they can attempt to stay relevant even if behind but Karma's mantra-fied 'E' is pretty much Sivir's ultimate and on a much shorter cooldown. It also has a shield on top of that so let's not forget how much better and satisfying it feels to use Karma's version rather than Sivir.

I would love if Riot looked into Sivir's ultimate ability and change it up. Play up on her 'battle mistress' and 'plunderer' fantasy and perhaps for a short duration have it give more gold on kills and assists. In order to prevent possible abuse give it a charge up time like Taric's ultimate ability.

My other idea though possibly broken given would be a team wide invisibility buff for a few seconds. It still purposes as an engage tool but like I said it may just feel a little bit too broken.
