Your guild is fine if you like it. You should be looking for the guild to have over 25,000 tickets per day earned, and you should be looking for a guild that's talkative and friendly.
I always have a little concern about the guilds of people who show up here asking for advice, because ideally you'd have people in your guild able to give you advice every single day. But you don't have to be friends with your guild mates, it just makes the game more fun (at least for me) and can be less frustrating if something comes up, because when the guild needs to communicate with everyone, there's already a pattern of people checking messages. People are obviously more likely to get the emergency message if they're used to checking for messages every day anyway.
But this game (like all games) is about having fun. If your current guild is fun for you, and if it can sim HAAT and Heroic Rancor, and if you're completing Heroic Sith, and if you get 25k-ish tickets, then it's ticking off all the basic checkboxes. Anything additional is up to you & what you like & what you think makes the game more fun.
