The AOE support ults are lame

With Invisible Woman and the buff to Dagger there are now 4 support abilities that provide de facto teamwide invulnerability to normal combat mechanics. Stop doing this. It's lame. Invisible Woman's ult concept is an interesting idea that becomes completely boring because invisibility doesn't matter when you couldn't kill them if you could see them anyway.

"We are undefeatable" is a bad ability concept. Drop it.
