Keep in mind that people often don´t RP their gameplay mains and practice of adding OOC alts to guilds from my experience is very rare. Therefore, you can easily end with situations where people in RP guilds only log during RP times because even if they play the game outside of that, they might be on completely different character.
Our guild, Azure Dawn, accepts both high and void elves, feel free to give our thread a look. We´re active and have multiple events + social RP every week.
