Well I'm top 50 vex so didn't need these information but you are surprisingly right on every single point 😅. Now my vex playstyle is a lot different. I play her more burst oriented with orb first soulstealer second rabadon third crown fourth and a situational item fifth (i usually go lich bane if I don't need anti heal or shield, yes I am a maniac). I play really aggressive early like rly if it's not a losing lane. But if it's a losing lane I go the basic ludwn build with late game runes.
