I’m not entirely sure what you’re looking for since it seems you’re more interested in a PvE guild; how much structured activities you’re looking for, big guild, small guild, etc.
However, if you do end up on CC/SoE you’re always welcome to join our RP community even no matter which guild you sign up with. We have an /AllianceOOC chat that’s pretty active in the evenings, plus several open RP events a week for casual walk-up RP without committing to long story lines.
