Make uniques useful again (abbreviated: MUUA)

I've always hypothesized that just by adding a random enhanced damage or enchanted defense to uniques would make them more viable in higher levels.

For example:
Splinterheart (uniq bow)
It is lv16 and (60-80)% increased Physical Damage

Just change the max damage 800%, and you can only roll the max when you are at the max level

lv 90 and (60-800)% increased Physical Damage

This would make all the uniques interesting to find and use

Should have said Make Uniqs Useful Again = MUGA

Should have said Make Uniqs Great Again = MUGA
