Melee generally refers to disorganized close combat involving a group of fighters. (Wikipedia)
It denotes weapons for use in hand-to-hand combat (such as a sword or club), in contrast to ranged weapons (such as a bow). (Wikipedia)
Confused, hand-to-hand fighting in a pitched battle. (thefreedictionary)
***a confused struggle***; especially : a hand-to-hand fight among several people (Merriam-Webster)
Melee is a form of physical combat that requires the attacker to be relatively close (arm plus weapon length) to the target as opposed to a ranged attack. (WoWWiki)
Want me to find more definitions? There's plenty out there.
2. Mage's wand damage stat is also increased when sharpen weapons is used in group.
I'm just confused what's with the wording.
Sigh. Yes, melee is defined that way and no you don't need to find more definitions. I was referring to the fact that 'a melee' can just mean one big fight (which means that yes most combatants are indeed of the melee classes).
I meant by #2 that: this wording is to emphasize the group ability of the skill, bc it obviously adds dmg to all.
