Couple of jumping puzzle critiques
Spekk’s Laboraty is completable solo. I have finished it without ever using another player.
Dark Reverie is a pain, but is not “elite only”. What you should do is equip a ranged weapon and start hitting the turrets (stay away from the pulsing ones and hit them down after the normal shooting ones).
As soon as you get near the ground, make sure you’re full health and out of combat. Run and roll and jump to the next part with a turret and jump onto those leaves. The other enemies will de-aggro and you can defeat the turret[s]. From there, it’s just jumping with a few turrets. Take your time, patience is key here.
I finished this jumping puzzle at a lower level than the mobs here, it took me a few tries, but I did it.
Spelunker’s Delve is also relatively easy. If you are having problems seeing, try zooming in. It may look ugly, but you’ll at least see clearly. Also utilize your camera angle.
All of these jumping puzzles are nothing compared to Scavenger’s Chasm. You’re just whining.
