    i am having two issues with the distance joint.

    I am using two joints, one on each side of a platform. I intend to have the character stand on the platform and reduce the distance to raise the platform.

    Issue 1 is that the anchors start pulling away from the starting anchor point

    Issue 2 is that if the character is on the platform and I raise the platform using the joints, the movement is sluggish like its lifting a ton even with low mass on the character. When I jump the platform speeds up.

    Any thoughts on the matter would be appreciated.

    All joints in the 2D physics engine (Box2D) are "soft" to some degree however know that you are free to increase the number of position/velocity iterations used by the solver and not just use the defaults. Doing this can mitigate (to some degree) this issue but again, it won't necessarily eliminate it.
