Champions trend in LCK

I wonder why the trend in LCK is changing too fast. In this split, the meta feels different. Ranged top champs like Jayce, Varus, and Vayne suddenly become priority. Annie also appears more in mid laner draft. The newest change is Anivia, all players in any role are flexing this champion in top, mid, or support role.

I thought we're going with bot lane focused meta this season bcs in early 2026 every team was playing around bot lane (bot lane became their priority in draft, and they played around bot laners to win the game). But why is it changed a lot now? Those champs I mentioned above become top priority again (esp. Annie and Anivia), and ranged top champs (with top lane prio) are popular now. Can you guys explain why the meta has changed like this?
