Runes need further work

1st guardian comes out of the resolve tree along with font and revitalize, they all go in a new support focused tree The resolve tree then becomes focused solely around actually being tankier be it resistances or health
the flex runes get more options instead of being solely adaptive force/armor/MR things like mana regen or health regen can be added as well as attack speed and health and a movement speed why? because as it stands its three 'flex' options you still only get 1 of the flex tree but its more varied depending on what you feel you need
then two secondary trees can be dipped into instead of 2 options from one secondary
it cuts down on the ability to abuse certain combinations while opening up new options as well (it would also allow omnistone to be tweaked around whatever 2 secondaries you have which might make it slightly less useless) It also could create very interesting options for many champions
more keystones would be needed in both the new support category and the now only 2 keystone having resolve category
this is my idea due to my disdain for both the lack of variety currently and the lack of viable options for some champs as well
