I think the biggest problem developers are worried about is game balance after adding new armors. If that's the case, then they need to remove/replace some of the armors we as a community do not use. The biggest problem I see comes down to looms.
lol... no. just no.
the game devs clearly don't give 2 shits about game balance otherwise they would have fixed the 'glitches' (i.e. hiltslashing, point blank lolstabbing) that are already present in this game. most of those happen to come from the 2hand class due to the funky animations making them swing uber fast as well. then there is always the fact that its arguably too easy for anyone to just pick up a crossbow and be an instant marksman. not to mention that 1hand stab glances 80% of the time at least.
I could go on and on, but basically... the devs have no problem adding new armor, they are good at doing that (however rarely they DO add them). they are only bad at fixing what is already broken.
in my opinion, they need to seriously consider fixing the fundamental gameplay before looking to add hundreds of new (potentially gamebreaking) features. i will admit, they fixed nudging in a decent amount of time... so why cant they just as quickly take a look at some already broken things?
