What is the point in joining a guild?

I have played a lot of online games, but I never got the gist of joining a guild. Usually it's a bunch of people seeing the game as a serious job. Other times, it's a bunch of people talking Reddit-like nonsense.

I'm not a group person, so maybe that's why I don't get it and thought I should even ask for an explanation here?

Oh and before you answer, I am never amongst the higher-end players in any game, because I always get tired of either repetitiveness (POH isn't a candidate so far) or p2p functionality (I'm hoping I can somehow manage to keep playing POH, but the 4 tabs is making it very difficult for me right now) before that happens.

So, one thing that a guild can help with is giving you advice about which items you can discard to save space in your tabs, and also as a place that stores gear donated by other members, so you have access to useful gear without spending currency, and it is stored outside your stash tabs, thus also saving space for you.

Wow, that does sound useful! How should I go about choosing a guild to join?
