-Free-running move-set(which does, differ from parkour moves, i.e. what this game uses)
-Dual pistols
-Dual knives
-Primary weapon melee weapons
-One hit kill headshots
There's probably a few more, like Molotovs, but that's already been discussed to no end on here. Now, I can see why there will be no free running because it's all about practicality, and one hit kill headshots have also been discussed rather abundantly. Which leaves us with DUAL PISTOLS, PRIMARY MELEE WEAPONS, and DUAL KNIVES. Now, to me the whole knife thing would just be pointless, as no one but little pre-pubascents would run around trying to play ninja. But, i don't see why there can't be at least one primary melee for at least one of the classes. TF2, which is probably the closest comparison we have to this, included melee weapons, and they never feel over powered nor unfair. Just saying, it could be done. And I see absolutely NO reason for not putting dual pistols in. I'm not asking for Halo's stupid dual system, just dual pistols.
