Can I have some advice?
I'm lvl 20 power 201. Just finished the story. I have a couple of hours this afternoon to play and I have any to catch up with my clan power wise so I can do nightfalls etc.
What should I focus on doing? Strikes? Cruicble? Adventure missions?
Which is most efficient?
Clear your adventures , do public events or crucible (whatever your fancy ) until you hit 265. After that do the weekly stuff for powerful gear (as it's stated ) . It won't take long to hit 265 honestly , you level up so quick compared to D1 .
The powerful gear will take you over 265 and all exotics and some legendary engrams if they have the right mod . Basically open engrams as soon as you can after you get them
Also do the planet quests (blue ) when your at right level . They reward exotics even etc that will give you a nice bump
