Is Riot ever going to work on range vs melee lanes?
Melee vs melee is fine. Ranged vs ranged is fine.
Melee vs ranged is an absolute mess; there are almost no risks to taking a ranged champion in a lane, while melee champions have a lot of risks. That's why the only melee champions taken in lanes are ones with either no mana, waveclear, ranged farming, sustain (or some combination of those).
Is anything meaningful going to be done about this? I mean I don't know how much longer we need to yell to get Riot's attention; this has been an issue forever.
Maybe making it so ranged champions take minion aggro the second they rightclick a champion instead of when the attack connects, so minions actually are a threat.
NEED TO BE AS SQUISHY AS -> 
catches you, you DIE. No questions asked

, (melees with gapclosers and damage), get to a ranged champion, THEY MUST DIE, due to their squisheness. In other words, "counters" to ranged in top lane.
Does this mean, that the above now become dominant again? No, buffing the base health/armor and armor per level of these guys
ensures, that melees with gapclosers don't become dominant.
and
is hardly a problem. If you meant
in top, then yeah. But Riot themselves said they're gonna change Quinn eventually so, ( and she has a low pick rate too).
