Not much has changed, i think they did runes/masteries in one take now as the only change?
Akali, irelia, Kaisa, Xayah, Aatrox, Rakan, Qiyana and pyke are pretty broken imo
Runes work much as they used to, get a read through them and figure out what you want
New champs are super broken, and have mostly gotten the names "season 9 champs" because the meta is just season 9 champs. They're really unfair to fight and bring way too much with their kit
- Katarina is a top solo q roaming mid laner, really weak laning phase though, you kinda need to get around that
- taliyah idk kinda meh mid/jg? she was meta for a bit then got nerfed and isnt really played too much.
- Fiora is ok but not super strong, personally struggling vs tanks that just buy armour and facetank you
- Sivir is really good, scales surprisingly fast compared to what she used to for some reason
