the level requriement should stay and most guilds figure that if you invest 30 level into a toon, you wont be as quick to jump to another class. A guild recruits you based on your class that you are, not the person behind the computer in most cases. Lets say you start a mage, and its easy to solo till your in your 20's.. but it gets harder and harder to level with out a group.. so lets say guild badbutts.. recruits you.. as a mage. When you realize that you cant solo, you go and switch to a druid.. well now your guild need you to be that mage.. but you didnt like it..
see why guilds dont want level 8 toons with no playtime.. things are different here then on live. you should group with people and not worry what a guild can "give you at level 8"
Learn the zones and how to get arround first..
All new players and toons are in a guild called Dalaya's beginings. There are some folks who are level 65 in that guild. they never left..
