Introduce barrel roll and I clearly see the future development:

Tournaments are not only PvP anymore, it will be formation flight contests (additionally?)...

Oh yeah. And let us buy color smoke for afterburners (as charges) to support formation flights!

And why exactly would they be against formations? Because it puts too much strain on the server?

I wouldn't mind seeing various maneuvers and formations added. Just imagine how awesome it would be to fly a group of Frigates through a barrage of missiles and gunfire, rolling around to avoid getting hit, and then after killing their target(s), doing an Immelmann Turn (for show) and then burn back to the larger ships in the fleet. It would look epic, but it would most likely kill the servers the moment anyone tried to do it.

let me reference the underlined part, and just say, NO! lets not encourage them to break physics more than they already are. you don't twirl about in a space ship. that's how you go about killing your crew.
and in reference to the bolded part. (I'm taking a line from the oatmeal here) in the name of zeus' thunderclapping butthole, NO. I'm pretty sure any time I've seen references to emote in eve, they have been shot down with the verbal equivalent of the initiation of world war 3. do you know why? look at wow, having to watch a crowd of people doing the same little r******* dance is just plain painful. it's not cute, it's not a neat feature of the game, it's obnoxious and mostly used to get peoples attention.

They did put a capsuleer shooting another while walking in stations in a trailer.

Also fourth dimension lol. If you really want to control your ships completely (as in actually fly them instead of click where to fly) you'd have to use a 3+1 axis controller (joystick with twist and speed select). On one hand it would be fun to some of us if EVE worked like that, but ultimately that requires twitch mechanics the game and servers aren't built to handle.

"Spaceship Emotes".

I want to be able to turn on my highbeams on my Harbinger while tailgating out of a station and annoy other pilots.

Taunt them in local - job done

And stop bumping - nearly nobody likes your 'cool' idea.

You might be aware of the fact that bumping is against the forum rules.

1. Rotate your camera so you are looking straight down
2. Double-click in space at the top of your screen
3. Double-click in space at the bottom of your screen

You have now performed a barrel roll

This would have to be limited to frigates and cruisers. Anything above that size, in my mind, would look like a beached whale turning.

We NEED barrel rolls.

Not sure how it is these days but back in 2006 the barrel roll emote was patented by EA.
