Hello, i read all the wiki etc but i found NOTHING on that...

So here is my question : What are the modifiers for Melee Weapon ?
Strength or Strength + Melee Weapon ?

I already know that for Melee Weapon, Max strength is halved to get the modifier for Melee damage.

Now, when it comes to Melee Weapon skill, what does it actually do ? Is it only a "pre-required" in order to wield a certain weapon ?
Does it add something on top of the Strength modifier ? More damage ?

I'm asking that since i plan to use the X-2 Antenna which required 75 Melee weapon skill and i don't want to spend the extra 25 Melee skills points to reach 100 M.Skill for nothing.

So far, i have found nothing on internet with calculation..
