How do I find a static raid group?

[Krr]

If you're on T5, buy your way up to T10 (or whatever your server's pug progression curve sits at) or find an FC that is actually willing to help you.

Strut your stuff there in PF. Post ads on your local server forums, reddit, et al and in your server's PF when you have downtime.

It's a sad truth, but few statics on heavily populated servers are going to care how 'good' you are, they don't want to retrain a player in fights they've already done, so saying you have experience in current content matters more than anything. A Dragoon with some Dreadwyrm pieces that doesn't even stick Chaos Thrust is going to look more appealing than you at first glance if you can't say you've been to whatever content the majority of your server is on.
