I still believe the fifth class has stealth & range speciality skills.
The class should have close combat skills as well, high dps or massive criticals, etc...
Ideally, it should be a Rogue/Ranger/Pathfinder/Hunter archetype that should play differently from the other classes.
Something that requires more finesse than the Barbarian or Monk.
for those who are positive the fifth class is a ranged weapon specialist, how might blizzard avoid falling into pitfalls like the guided and multi arrow that they had to nerf eventually anyways? any creative ideas for ranged weapon skills that could really instill some new life into an arguably archaic rpg staple
Give the specialist aura based skills that magnify the range damage, slow enemies down, etc... instead of arrow augmentation. Limit the aura radius and have abilities given to enemies that negate specific auras to spice up the challenge. I'm sure Blizzard will come up with something great.
