I have to agree on the Skipping Lock part. I have died multiple times trying to slide through a passage and then never get enough momentum to land the jump end part with my Warlock, who glides past the edge (mantle isn't working) and falls to his death. But I have no problem with my Hunter or Titan making that jump.

Then there is jump into grav cannon get killed, make it there jump in grav cannon and fall to my death as it does not recognise that I jumped into the beam.

That happened to me as well. The other one is platforms that aren't there, like the special ones you unlock.
