Twitchy Questioning 3: Return of the Twitch

Of course, sorry.  

Melee-focused, built around shotguns and pistols, point-blank powers, or both.  Feel free to rephrase- the intent of my question is to call into focus the fact that melee gameplay feels unrewarding, even if it's technically effective by-the-numbers, because of a combination of factors:  the great deal of fire it exposes you to(particularly jarring for having to sacrifice durability for melee damage or vice versa), the extreme mobility of some enemy types(observers, obviously, but raiders, assemblers, and sharpshooters all kite to an aggravating degree with no loss in speed or accuracy), the sync-kill threat of other enemy types, and the seemingly-counterintuitive stagger weights evident in any fistfight.

EDIT:  Also, looking at the list up top- I was actually talking about player races in the design philosophy question, although I'm sure they'll be eager to answer the one about enemy factions

As always, kudos for your skill at diplomatic phrasing.
