Question: Getting armor glitches fixed?

I was just wondering where do we report armor glitches to Anet so they can be fixed? And if it is an old armor glitch (factions) can Anet still fix it?

I came upon a small glitch on the 15k Luxon gloves for the male necro. I noticed it awhile ago but thought nothing of it and thought Anet would fix it, but now it is starting to irritate me. It is just a small glitch but it is noticeable, here's a pic:

As you can see the tip of the pinky on the right hand has been bitten off and is missing. I know of the armor glitch thread here on guru and even posted this glitch there, but the glitch is still here and I was wondering if there is anything I can do to get it fixed?

Any help would be nice.

There's also a glitch in some ranger armors when sitting. I have a screen of 15k Luxon, and the behavior occurs in regular Luxon as well:


Also (and I don't know if this is still the case), it used to happen in Druid armor as well, which is displayed in this screen:


I'm guessing it's a flaw in the ranger model?
