Make Courage of the Colossus only proc when two or more enemy champions are nearby

Right now Courage of the Colossus outperforms Grasp of the Undying in pretty much every way as long as you have the hard cc to proc it. Currently it's:

• Better in early game trades and 1v1's in general
• Better outside of lane
• Instant as soon as the hard cc lands

While Grasp of the Undying is

• Unnoticeable outside of lane
• Delayed for 4 seconds into combat

If Courage of the Colossus's power is taken out of the 1v1's Grasp of the Undying might have a chance of having its niche back. One way to do this is, as the title states, making it only proc when two or more enemy champions are nearby, making it absolutely worthless in 1v1's as it probably should be. Another way is to make the shield scale off of bonus health so it is less effective in the first few minutes of the game, although that would change as soon as the first health item is bought.
