Melee-only servers are interesting. If you are good with a sword, please join one. Its more interesting than most.
For example, there is a map where there is this massive pit thingo. I fell in, but hanged off the cliff wall. All my teammembers died and I was the only one left standing. So I climbed back up (with effort) and died ^^.
Moves:
Double Tap in a Direction: Matrix Style Leap in that direction (with sword, dash)
Jump > Right Click : Hang off wall
Run towards wall > Jump : Run Up
Run 45 degree towards wall > Jump : Run sidewards.
These are a little of the moves.
