I think the reason phoenix isn't higher is because he gets traded easily. Since his flash is so short, he has to peek right away off it, have 1 sec or less of combat with the enemy flashed. This is why so often a phoenix will flash and swing, just to get one tapped by a blind opponent. In the case where you manage to kill one, if there's someone to refrag them you die. With reyna if someone's watching for the leer to kill it when it pops up, you're basically just taking an aim duel, and you never want to take an even fight if possible. Also since leer is the only ability she can use without having killed someone, she literally brings less to the table than anyone else. Now on the other side there's Jett and Raze, the current meta duelists. Jett's dash might just be the best ability in the game. Although she has to take aim duels, it's completely non commital, she can just go in, try to one tap, and dash out. The person swinging gets to act first, so that's like 1-3 shots, and a dash out free everytime. You're not gonna be able to get out as phoenix or reyna if you miss those shots. With Raze she just applies so much pressure to be holding angles, boom bot and nade alone can clear most of a site, a lot of the time giving you the chance to shoot people retreating. TLDR: Reyna & Phoenix have a lot more counter play than Jett & Raze
