I care about the traits but if a hotfix makes what I have worse and something I tossed better AND it’s not just a tiny difference then I’ll just restore that item. This has only happened a couple of times over many years of playing. I also have bank space and often pile up things I feel are important until I sort through them and then do a mass bank-space-cleansing.
A lot of changes just come with patches though and that likely means new gear, new sources, and higher level stuff so unless it’s a huge deal I’ll just get the new stuff.
