Here's a potentially manageable suggestion for you zos - can you make it so that when you are wearing a costume from your collection as well as a guild tabard, the costume is still displayed? This would make a difference to me as I run with guilds fairly often and don't like my actual armor much. Wearing my guild tabard over a costume would look way cooler than my missmatched gear ( I hate the Bloodspawn helm - wish it didn't have a faceplate).
I can almost guarantee that this has been discussed in other forums but I haven't seen it.
Oh and by the way, if you can't do this then no worries, I know you guys are busy and I appreciate you. Tired of the hate on the forums.
