The idea is to create an actual trail of rainbow which follows behind the character as currently the rainbow footprints are rather dim or difficult to discern in bright light conditions. Additionally some sort of rainbow projectile for ele/mes/necro as other legendaries have been receiving animation buffs. These are all suggestions as it sees implementation of legendary animations is at some level happening inside the anet dev. team. Sure there are more deserving legendaries such as “The Bard” that need improvements much more badly however Bifrost still feels a under pronounced in visual effect when compared against Twilight/Sunrise.
In conclusion Bifrost could be so much more, it could truly be what an Legendary is, .. Epic. Bifrost if compared to other staffs doesn’t actually stand out that much more, the aura is literally the only defining feature. Though the staff itself is rather beautiful, the white base works against the encompassing rainbow and somehow de-saturates the visual effect on the staff. I can understand the difficulty in implementing rainbow colours on white or even a mid tone which would work against the rainbow effect on the staff. Though a possible solution is the use of contrast in the brightness of the staff or on the tiny floaty stones to accentuate and give it contrast to pop and stand out in a crowd as a legendary should.
Below is a sample of bright shiny geometric shapes, though they disappear in the light, Bifrost could have some with sided shadows to make them pop in the light.
