Why did Vi go from a nearly 0.1% pickrate for nearly 9 years in a row to 50%+ presence for the last 3 years? (ESPORTS)

Title. I have played League since season 2, so I am a veteran of the game and also a masters + player.

Something that intrigued me upon looking up the GOL.GG stats is that Vi was nearly never picked in competitive play in any pro league after season 4 until season 2022, when Vi, without substantial changes to her kit (whether in the form of a mini-rework or buffs) became 30%+ presence in pro play at 2022 worlds.

Now some say this was in response to the meta at the time. Ahri and Zeri were power picks, and Vi was a counter or synergized with these champs, hence the fact Vi became a common pick.

...but moving forward into season 2023, 2024 and now 2025 Vi has remained a pro staple even upon receiving substantial nerfs and through various meta changes.

Were pros really just ignoring that Vi was a powerful champ all along? Could teams have had success playing Vi in seasons 7, 8, 9, 10 for example?

Or did the game change in some fundamental way that I am missing? Rarely does a champ go from nearly 0.00% presence to being an LCK and LEC staple with only minor changes to their kit.
