Yeah this is what I fear too. I feel that they should FIRST implement everything faithfully, THEN play around with homebrew stuff.
That they did not do that, shows that they have not much respect for the 5e system and they just want to do their own thing, and they see the 5e brand just as a marketing asset.
They are using the names from the D&D rules, but what the stuff does in their game has not much in common with it.
When they would be honest, they would change the class system. Then you would be able to choose between the following classes:
Pit Shover
High Ground Jumper
Magic Missile Spammer
Backstabber
I guess then everyone would have a better idea how to build characters and what each character's purpose is in combat.
