No no, you're fine. You bring up a good point. A whole team of solo bubbles sounds like a nightmare in a game like Rift. So maybe a really greatly reduced duration for the solo bubble [i](AKA Veil of Light/ Personal Bubble)[/i] Also you couldn't have Armor of Light, Blessings of Light, or Weapons of Light, as Veil of Light occupies the same perk column. So they could pop pretty easily with a good flank.
