Veteran player returning after 1.5 years
You missed out on 4 episodes of the living world (episode 5 comes out in 2 days). That’s about it I think.
Getting into fractals just get your AR up and go kill things. It’s not that hard really and they seem to shower you in rewards now (I got a weapon chest last night, first time stepping into fractals in a few months).
Raids – it all depends who you ask. I’ve heard a lot of horror stories of elitists demanding 930483098 legendary insights and full ascended gear and ping your legendaries and DPS meters all that. I’ve also heard you can just pug it as long as you have exotics or better and know how to play your class.
I haven’t really tried to get into raiding yet, but I’ve heard of guilds clearing raids naked… so the gear requirements can’t be that intense. It’s probably more a matter of learning the fights and “git gud”. My advice: try to get as much ascended as you can afford, and watch some youtube videos to familiarize yourself with the bosses. If you do a lot of fractals, the gear should be no problem.
For a cursory review of what’s been added in the past year or two, you can use the ‘Releases’ link above.
Welcome return, and good luck.
