I think its only fair to add some ranged options in Eldritch Knight since a couple months ago ranged options were added in Paladins Knight of the Chalice.
All that needs to change is making a ranged version of Eldritch Strike so ranged builds can use the capstone enhancement and be able to activate Eldritch Blade. Also add doubleshot alongside the already existing doublestrike and changed the rest of the skills that only work for meele to work with ranged as well.
