I really like Crystal personally. I've been on Malboro for 3+ years and it's great.

The raid scene isn't as strong as it once was but will continue to grow slowly. If you have friends or an FC you can still savage raid fine and I see pug groups up all the time. Ex trials are fine as well. I also notice that on Crystal, prog parties seem to stick together longer than what I've experienced on primal for example. Meaning that after a wipe or two, the party just isn't going to disband which can be annoying.

The hunt scene is also great on Crystal. Malboro has a great hunt community and Crystal overall is really good.

I don't RP but I always here good things and I have a few friends who do and they enjoy it.

Also, if housing is your thing, you're more likely to find housing on Crystal which is really nice and can also play into your RP goals.
