Wild surges

So, this may be a better post for mod discussions, I'm not entirely sure yet, but moving.

Not to long ago I was looking at the wild surge table charts and I noticed something, we have too many overlapping affects.

Two targets held, two fire balls on caster, and even two variations of color change. Wod it be in all possible to change some of these affects and add in new ones? Both good and bad?
