If I had to estimate I don't think we'd have a full group running 5 for another month. A few people are just starting to run 1 and 3 at the moment. The vast majority of our FC only started playing at the PS4 launch. And even if we're not a good fit for you I'd still suggest giving Behemoth a look. It's high pop and there's tons of FCs running T5 and up.
