I hate to say it, nut there is no real one way to do GW. It all depends on who you are challenging, their power and strength, how many players show up to actually fight on each side, who is placed where by the city owners, and so on. You need to learn who your rivals are, and how they play, look at how many cities they are defending and against whom, and have a good strategist at the helm. The forums and wiki's don't have alot of info on this yet, as the game is still so new. Haven't checked YouTube to see if there is anything useful there. The Evony and similar Pvp game wikis may have better info than here. If you are just starting into guild warfare and have no experienced players on your team, it will be a bumpy ride for a while, until you learn the moves. More bodies is always a good thing, so try to encourage as many guildies to show for GW, regardless of their power of level. Keeping chatter in guild chat so no one misses and order is important, as is making sure that your players don't chat fail in realm and give away your plans to a rival. Commands given in ALL CAPS catch attention better, and answers in lower case, y (yes), n (no), ?, R3 R2 or R1 for recover rounds at base so command knows who will be able to move when, or just simple 3 2 or 1, and r (recovered). Play with it and find what works best for your players and their attention spans and personalities. Keeping track of how many kills each player gets, if any, before they are killed will help command know how many rivals are out there. And never count on it to stay the same. Players can enter late, leave early, and rivals my have a huge number join from another city they were battling in and finished. Pay attention to the world chat announcement banners. You may get a heads up that your rival has finished another battle and is about to come in force to kill you off. Lol! Not much you can do about it, 'cept brace for impact and grin.

Good luck to you, and don't worry. If you lose, you still get rewards. And if you all pay attention, you will figure out your best strategies. And have fun with it.
