Where do you get this idea that melees are avoided?

Me·lee  (mā′lā′, mā-lā′) also mê·lée (mĕ-lā′)
n.
1. A confused struggle or fight at close quarters. See Synonyms at brawl.
2. A confused tumultuous mingling, as of a crowd: the rush-hour melee.

Melee's only happen outside of formations, I.E, when all chaos and hell's breaks loose, and you're in a position you can't tell friend from foe.

Yes they were avoided if possible.
