As you look him up, you'll see his main is already in the guild.Are you even able to invite to the guild? Without being able to do that, your main will not be able to join the guild and you cannot exploit items.
The first posibillity that crossed my mind was, being able to faction change this Trial Account character now by using the Guild faction change feature.
You can't use any paid services as a starter account, although I did manage to get a free realm transfer to work. Those aren't offered very often though, and it was just to a South American realm, not a lot of use. I only tested it to see if I could.
You get a guild under your name. You can change the guild crest. You can type in guild chat. Those are the definite advantages. The guild bank is a possibility if you can ever get that to work. Apart from higher level enchants, there's also mats and various consumables that are easy to get with an 85 but a pain at 20. If you ever level the guild, there's also guild perks.
OMGGGGGGGG i'm sooooo jealous

By the way Aradiel, I don't seem to earn Guild reputation through playing Battlegrounds, unfortunately.
