with the right build, it's not too hard to get close the the enemy, dont even try to debate that. The only Problem is as I said that you still can't do much when you are finally in front of the enemy.
Basically, the best melee char istill has less dps than a throwing char with 15range.
Also, even if the enemy is unable to 1hex you, he can still run. Due to the laggy engine you can always run away from a melee if you know how to.
All in all, your suggestion does not solve the problem, it is the wrong approach. On top of that it greatly interferes with other aspects of the fighting system that don't have to be affected in the first place.
Bottom line, no.
