Hey
Thanks for your feedback! I guess I should look into Strike missions at some point. When they were introduced I kinda placed them in the same category as raids in my mind and didn't bother trying to get into groups (also I don't think I played actively when they were new). I still want to get into raiding in the future, but at the moment I don't have a lot of time to play and training groups tend to take a lot of time (I joined a few in the past, but only managed to get through wing 1). I like your idea of just joining random groups and asking whether it's ok though, I might give that a try.
For now, I'm slowly working towards Ad Infinitum. As I mentioned, I mostly do Fractals at the moment, so collecting the Ad Infinitum parts seems like a sensible thing to do.
I agree, PVP and WVE legendary armors seem easier to get. I never liked PVP though. WVW is quite fun for a bit but playing it exclusively tends to get boring. Anyway, getting legendary armor is a rather far goal for me at the moment, but as you said, there are still a lot of other things I can slowly work towards before getting legendary armor.
