best advantage

Mouse&Keyboard FTW!!

I would say all the above! on top of that, i would also say, where you are versus where your opponent is!  Usualy always better to have altitude on your side, i.e. being higher than your opponent is!  Execution is another thing, knowing the best weapon for the current situation, i.e. if come around a corner and expect some one to be at a great distance, i equip a hitscan weapon!  If i am giong to say , heal a node, i equip a link gun before getting on the hoverboard!  Another thing i like to do, if i hit some one with a rocket, quickly switch to your enforcer and finish off the job, a direcrt rocket does 100 damage, if they had armor, that leaves 50 damage left for your enforecer, the enforcer does less damage but has a high cyclic rate on its side! my two cents!

lol yea thats more like a dollar 

As a heavy vehicle user, I like to know the capabilities of each. For example, when using the tank, you don't have to have a direct hit when killing someone. You can aim at the wall right next to them or the ceiling. Even when a manta comes towards me, I never aim directly at them, I always aim to the ground.

Luck.

knowin how ur opponent plays..   cuz in duels, weapons have spawn timing so if your opponent has the shock, sniper, and rockets, and u have flak, bio and link,  you're better off knowin how he plays unless you happen to be a dirty bio rifle dude or a flak king / alt stinger kid... if you are more skilled than ur opponent then you will know how to use ur weapon, even if its u using an enforcer versus his or her rocket.... surrounding ties in with timing because that shield belt will screw u over and over again.. if you're playing someone that half decent, it doesnt matter how good of a player u are.. ur most likely going down of u dont know where to go and how to rebound urself

You guys do know that Remy pretty much covered this in his Duel guide? You guys should check it out in the Tutorial section. The info in there can be applied to all modes. Just a thought

Flak would work well too, an individual shrapnel is like 15 hp? Enforcer may be quicker. nice one

Enforcer = 20 AFAIK

flak = 18 per shrap
