Not a problem. Good luck finding a guild that works for you. Many of the upper tier ones will wait to see if you're going to be a dedicated player. Some also have points and PvP minimums. However, just because a guild is big, doesn't mean it's better. How a guild is run is a huge factor in how helpful it will be to you. In Cirgard I moved guilds multiple times before I settled into one that functions the way I'm comfortable with.
