Assault Kick isn't bad, but it's not worth getting because it's rendered obsolete by Reflect Kick and later the Wind Sneaker's Slide Double Kick. Meanwhile, Railstinger's power and piercing ability stay useful in PvE even at the level cap.
Aero Tornado is a powerful single target 300MP skill. You can't compare it with Phoenix Strike because Phoenix Strike is used as a long ranged attack to clear rooms. You CAN opt out of it because Combat Rangers get Violent Attack and Sniping Rangers get Gungnir, but it's not completely useless.
