Thoughts on a 5th set of runes

It would be cool if We got a Green set of runes that were entirely utility based hp regen mana regen energy regen time spent dead movement speed new* Item Cooldown reduction 2.5% new* 1 less damage from jungle monsters

It makes sense since reds and quints are generally used for offensive stats and yellow and blues defense, well Greens will just be the go to for utility.

They could make green also have offensive stats but make them highly gold inefficient so most players gravitate towards utility.

There could even be a special green quint slot that triples the power of the green rune you place in it

Just a fun thought i had, setting up a rune page is one of the best parts of league and giving us the option for utility would let us test all kinds of builds without sacrificing any offensive or defensive stats.
