I would recommend your friends look at a guild like Conflict
They are mainly a black zone guild, but they welcome new players and take the time to teach them. They are one of the most well known guilds, and recently won the end of beta Castle Event. Conflict also has its unique logo due to winning an event in the previous beta too.
Conflict lets you focus on what you want to do. At launch we will have 100+ players with legendary packs and will also have a strong alliance to work with. This will give you and your friends the best experience, as you won't have to worry about upgrading your own buildings by yourselves, and you wont have to worry about being able to craft every piece of armor by yourselves.
We offer PvP practice, small scale and zerg vs zerg PvP practice. We also let new players form GvG teams, and we pay for your battles so that you can practice your synergy and composition. There is also a place for people who want to focus on just gathering, just farming crops/mounts/potions, or just want to do PvE.
