Welcome to the Weekly Question Post on c/guildwars2!
This post is dedicated to those questions that you might not think is worth making a whole post about, but sure is worth getting an answer to ;)
Remember to also take a look at the links in the sidebar, which holds lots of great resources and information.
Raiding/Fractals/Strikes might be tough to start as a group of 2-3, but you can look for learning groups until you feel confident enough to just join randoms.
I learned to do fractals from following guild members back in the day, and now that I’m coming back after a 6 year hiatus, I’m just doing tier 2 or tier 3 dailies and enjoying them again. Strikes and raids require a bit more work, but they’re quite doable as long as you have a good teacher and can manage your mechanics on top of your role.
