Advice on Troll's End
One thing you can try is orienting your camera to look down at your feet. You can move right up to the very edge of the wood plank (and even a bit over it) before jumping. This is usually what I do if I have to run the puzzle and there aren’t any Mesmer porters.
if it’s the jump im thinking of then there’s a trick to it.
One of the jumps has you on a wood plank, and in front of you are several stalactite (the ones that hang) it’s a deceptive jump, because the wooden platform does not appear to extend beyond these stalactites, causing you to jump before you reach them, collide into them, and swiftly plummet.
The trick is of course to defy conventional physics, and walk past them, the platform extends slightly beyond them (you can have about 70% of your body hanging off in mid air)
Then you jump.
This makes it a lot easier.
There is only one jump I have issue with in that puzzle. A while ago I realized that you have to jump a bit to the left rather than straight ahead. This is two jumps before you exit the cave.
Edit: This is the same jump Zenyatoo is referring to.

A good trick proposed is to use some tonic that transforms you into something smaller… like the tonics from Crucible of Eternity.
I play norn mesmer, so I always open a portal in case I cannot make it.
