As the title says
Nearly all cloaks are not worth wearing after a certain point because you are better off having two separate gear pieces with their own gildings. 2 slots as a baseline would help to make cloaks more viable later on
I think that silk clothing has been devalued in hafen because they no longer give base stat bonuses (int from merch robe) and take a lot of effort to make just for the chance at opening a 2nd or 3rd gild slot. These items should also start with 2 open slots on creation imo
