A Compromise to make Morgana a little more viable, without actually making her OP
Here's a simple proposition for Riot, to get things started:
Increase Morgana's attack range!
https://leagueoflegends.fandom.com/wiki/List_of_champions/Range
Notice where Morgana is on this list?
Only 4 Ranged champs have a lower auto attack range than Morgana: Thresh, Rakan, Urgot, and Mini Gnar.
Let's look at that list: Thresh: has gap closers, extensive pull control, scaling armor, damage, as well as the most usable ally relocation tool in the game (Sorry Ryze; yours is an Ult, and has a charge up) Rakan: Relocates himself, speed boost, and is actually a SUPPORT. Team heals AND shields. Urgot, Relocates self, tanky, one of the highest dps in the game, low HP execute, Shield that's almost spammable, disrupts skills, auto attack speed/range boost on W. Gnar: more of a bruiser, compensates with a % HP damage Boomerang with a reset capacity.
Why is Morgana, one of the universe's most powerful species, an Angel, who has one of the weakest damage sustain abilities......outranged by the entire League roster?
To put this into context:
was recently buffed from 575 to 625 Auto attack range! The little girl has a better auto attack than the adult angel!
Should Morgana have a longer auto attack range?

are in the same boat, having some of the worst Auto-Attack animations because of their farming power through high Damage AoE abilities or spammable one-target spells, forcing them to exhaust their resources on farming. Otherwise, they would have an easy time in the lanning phase, making them oppressive or impossible to engage on as they scale into late game.
