All melee champions should just have 175 range at this point
It's honestly pointless to have some melee champions with 175 range and some without. Yes I understand it would mean you'd have to change a lot of auto attack reset spells or range enhancers but 125 range doesn't even give you the abilit to juggle creep aggro.
At this point, there's no real reason not to. And melee champions, whether tanks or fighters or assassins, always have the burden on themselves to deal with ranged champions (obviously there are some exceptions).
Please just do it, riot.
