Re: I was thinking...
The idea is not very original. I have the seen many similar ideas like yours. I think these engineer class or a class with guns have no part in d3. People with these ideas need to play call of duty or halo.
What I would like to see is a class that does not resemble anything like d2 classes, wow classes, or a warcraft 3. Something new never seen before like on the lines of a Spawn type character. A character who was born of evil but transformed to fight evil instead. He would have spells such to enhance his armor and weapons. For example, spiked weapons, armor, and skin. He could also cast chains that reel in his enemies and simultaneously cause damage. He would specialize in the sword such as different types of moves kind of like zeal such as the paladin. Im could go on and on haha.
