I believe the input buffer has been extended and it does not feel good. As a Warlock I find that whenever I activate my glide right before my character's feet hit the surface he jumps. This is not a proper input buffer, as the glide ability actually activates before the jump. A proper input buffer would override the glide and just give me a jump. Other times I will deactivate my glide before I land on the ground and it also causes my character to perform a hop.
This feels really bad and in many instances has gotten me killed because my character is stuck in a short hop with no momentum, becoming a sitting duck in PvP and endgame PvE.
