I just recently started a guild, and its growing very quickly, which I am very proud about. 22 members in 48 hours, a website, and 2 officers I can trust is great.
While I'm new to the guild thing in SWTOR, I have been a guild leader before. These are the things I would like to see in the future.
1. Personal Guild Instance: Me and my guild want an instance of our own where we can gather for guild events and discussion. These would similar to Guild Halls in a certain other MMO, cause I know you don't want me advertising,
2. In-Game Calendar: I want an In-Game Guild Calendar to organize guild events and to alert guild members that they are approaching automatically.
3. Event Organizer/Creator: I have never seen in an MMO the ability to create guild events such as lotteries and the like. An event creator would make my life easier while keeping members interested in staying in the guild.
4. GvG: I still have not seen any for of Guild versus Guild PvP in this game. At least I haven't seen it, if you have, that's good. Perhaps direct me towards it. But beyond just being able to face other guilds, a GvG leaderboard and GvG tournaments in PvP would be great. I'm a PvE focused guild leader, but I think this is a request everyone would like.
5. Guild Emblems: This is another thing I would like. There is nothing inside the game that identifies the guild as solidly mine. I want an emblem creator so that I can identify my guild to others at a glance. Along with the emblem maker, some kind of piece on my character that has my guilds emblem on it that anyone within the guild could wear would be great. Not a cape, but maybe a shoulder-pad, or even an emblem display next to my player name in-game.
6. Increased Text Limit on MOTD & Guild Description: The text limit on the MOTD and Guild Description is far to short, and doesn't let me include all of the information I need. Increase it by 300-500 characters and it should be great.
This is all I've come up with for now, but I'll make sure to keep more suggestions like this coming.
