Not sure what all the changes were from the beta couple of months ago and the current multiplayer, but blind fire-then-melee is out of control.  Literally 80% of my death are someone running up blind firing then meleeing.  Hardly anyone uses the aim L1 button.  The medium range guns have more recoil and the players don't slow down after taking damage with increased health have turned U3 muliplayer into this melee and grenade spam fest.

yes just read the ND forums.
people are complaining about that like crazy, also the G-mal.
they nerfed it, even though no one asked it to be, people want it reverted back.
most people want it much more like the beta, the beta was so close to being perfect.

? hopefully things will change before launch. sounds like some adjustments are in order.
