Showing all weapons/armors ingame

But now you have to make tactical decisions on what you bring with you to the battlefield

This is pretty much how I see it as well. Now you choose a loadout and decide, this is what I'm going to bring to the table, this is what I have to work with. Instead of having it open where everyone could change gear better suited for certain waves.

Personal preference I guess, but I quite like the system that's in place.
