I've been doing some thoughts about this subject alot!
first of all, there's 3 x cloth users, 3 x leather, 3 x plate but only 2 x mail users.
so I think the next class will be a mail user.
Then we got Tokens for Tier-bonus.
2 out of 3, requires 4 classes and the last one only 3... so this last spot would be perfect for the next class too.
To the class itself, I think maybe a Tinker class would be perfect.
A Tinker class is a ranged dps / healer class who uses his Mechanics.
Stuff like: Turrets, Granades, Traps, Lazer, Rockets, Bombs you name it.
Would fit very well into the story aswel. ( Gnomes and Goblins have been tinkers for a loooong time )
And something with Engineering too.
