## Description of the bug
Be clueless marine, have ledge between you and warrior, warrior lunges you, but lunge cancels due to ledge being in between.

## What's the difference with what should have happened?
Ledges should not cancel warriors lunge, since it can be abused on maps with many ledges, Hybrisa caves for an example which is nightmare for warriors.

## How do we reproduce this bug?
1) Stand cluelessy
2) Have That's a raised metal edge next to you, south for an example, so it is between you and the warrior.
3) If warrior tries to lunge you, lunge cancels because ledge counted as an obstacle(?)
