The Gunner is a LA Human class gender-locked to female. The skills are fairly similar to archer but with traps to use in melee range and they use Guns. They are a little light on control skills but have high damage and great defenses.
The Paladin is a HA Elf class with dark wings gender-locked to male. They use a sword and shield. They have a "shield energy" needed for some skills and can switch its damage type from physical to any of the 5 magic elements.
Both classes have skills that can be used while stunned.
It will likely be another 6 months before they come to PWI, expect them to arrive around mid 2019.
If anyone wants to provide a proper translation for the skills post it here!
