What is with the melee air attacks?

Every video i see of most of the top players in this game they all do a melee attack in the air as they are walking or flying to combat.

What is the point of it?

Shammas does it in his videos
F5in did it in his as tank..

Melee attack after a kill is similar to a taunt. That's why I do it anyway.

no this is before anyone gets killed and everyone is moving out of their base etc...
Let me give you an idea

he does the grapple

but theres times when people do the melee all the time before attacking someone..

It's a habit. I melee air when I'm Tank or Gunner. I shoot air when I'm Assault or Sniper.

Well im not a top player by any means but i always will jump and shoot/reload as assault... just for no reason really. i will jump/melee as support just for wahtever reason...
but this may be ticks... i usually shoot because i like inf ammo. and i think it started early on as i would just spray etc.

just a little thing to do out of boredom. this game has infinite ammo so there is no reason to worry about losing it.

i thought it was check for lag

Its just something people do. I wouldn't worry too much about it.

I also wondered this too. Even tried it in a private match. After 30 seconds of melee'ing the air I left cause It didn't do anything lol. I thought it gave you bacon or something.

most time when im in a game im doing this melee shooting grapple stuff keep my rhythm on..

i think thats the reason many people doing it...

most time i never recognise im doing this **** XD

just for your rhythm i think ..

I think Pandoras got the right idea, im almost constantly shooting/meleeing/jumping. I dont know why but it keeps me ready to shoot some ****.

I usually melee as an assault if i'm near a corner so I can corner shoot. Your gun moves to the left side of your body so you can corner shoot easily.

It also looks funny if you melee and shoot as a sniper with the sniper rifle :lol:

True about the sniper, but I melee and shoot in the air to keep my grove on as xeno puts it.

I do this shooting and like everyone else jumping out of habit. It's very hard to break.
