Not only that but mnk needs to act cautious when attacking as they have no easy way of escaping. If your CDs are down you are being risky and death is almost certain unless you got some backup. You could sprint and throw away your TP...

Fists of wind helps somewhat with the range, but even then most of my attacks wont go off when I chase someone. lag perhaps?

When I try to hide from a range dps, the hit detection for the range dps seems very forgiving. Even though I'm clearly not in line of sight they still somehow manages to hit me. When it's like this why cant melee range hit detection be a bit more forgiving?

Again, this could be due to lag.

1 way of making it easier for mnks would be to make positionals work from the flank AND the back during pvp, as it is next to impossible to predict player movement.

Especially during 72 man slaughter, when drones are up, range dps clearly has an advantage over melee.
