Swordsman skills have the ability to dive toward another player. They seem to be a longer range than the Fighter skills.
I think it would be nice to balance how much range these skills have, as this is directly related to how effective they are in PvP.
I also notice that it can cause a problem in PvE, where you miss completely on your skill and it goes on cooldown even though you were not in range to use it.
If anything, not putting a skill on cooldown when you are out of range would be another nice resolution for this.
Of course, these suggestions can be taken in either PvP, PvE, or both contexts. Up to the developers!
