Phase rush needs to be balanced

Hello,

First of all phase rush is not used much. Only few mages use it. But meele range champions don't use it anymore. I assume that phase rush is not a rune made strictly for mages. Something should be done. Personally I think that tenacity should be added (for meeles only). Why? Currently if you take "legend: tenacity" or "unflinching" you have only 1 more rune remaining on the secondary tree. But what if I have more use of other runes that are on precision or resolve tree? what if I have more use of domination or inspiration tree? Then rune I would like to use(phase rush) is not really available on meele champions. Mages and adcs don't need tenacity as much as meeles need.

Correct me if I'm wrong.

Make me know if its getting buffed.
