Personally, I hope they don't. Every class has well defined weaknesses, adding swappable weapons in any form will blur the lines and muddy the waters and make some classes absolutely overpowering. Secondly, I like being able to look* at an enemy Pro and instantly know what it's capable of and how it behaves. Having too many weapons and addons and doodads makes it confusing for me. * Being able to see what Endorsements a Pro has without having to die to him/her would be much appreciated.
