At the moment, we're trying to get as many people geared and unlocking sectors as we can. We're mostly looking for tanks, leather DPS, and mages, so if you're one of those classes, and you want to join, you'll have less competition for A4 guild runs. However, we do accept all classes and urge everyone who's interested to apply. :)
Keep in mind that the amount of A4 guild runs you get into depends solely on how much effort you put into gearing up and participating in the guild. I've noticed a trend where people leave good end-game guilds because they feel that they aren't getting enough A4 parties, and I usually reject those applications on the spot. A4 takes hard work to succeed at no matter which guild you're in, and if you want to raid with us, you need to be able to put the effort into your success. However, we do try to share with you our tools for you to succeed with.
With that being said, we have a lot of fun in the guild, have a lot of fun conversations in guild/voice chat, and even though we take recruitment pretty seriously, I don't think I know of a group of people who enjoy the game more than the people in Esperanza. If you're looking to have fun in the game and don't mind that most of us take a shot every time we complete an allod, then Esperanza is probably the best guild on the server for you.
