Asking for compensation when you yourself isn’t a paying client is absurd. Even if you’re a P2W player, a buggy guild chat shouldn’t stop you from accessing the premium content of the game. The other two rooms are still there. The PM system is still there. Most MMO’s have their own built-in chat system.
Unfortunately, Dream World lacks a good in-game chat system. I’m not saying it’s impossible to chat with guildmates, it’s just so irritating when all the said bugs work against you. I agree that it should have been tested first, or a note saying “This is in test phase while we work on something incredible to serve you better!” …or something like that.
