Replacing spawn weapons

That means, no redundancy but simplicity and no illogical stuff [...]

Thing is, propositions that go here have little to do with simplicity, lack of redundancy or logic. It looks like the whole functionality is to be preserved, except its going to be squeezed into a complex spawn weapon and sold with new gfx effects. Now for that, I don't see any reason except, perhaps, desire to have something that looks brand new.

If the goal is to have simplicity, logic and lack of redundancy then its the functionality that should be cut. And I belive there are avenues for that. Regarding spawn weapon, I think either shotgun primary or melee should go. Which one of these, is a matter of testing the gameplay with relevant changes.
