In my honest opinion I think it is easier to get kills as the enemy will pointing at the centre while your at the bottom Allready shooting him , but im not a huge fan of it when someone uses it against me.

I do it just to get people mad. Because I'm a bad ass like that.

:3

Honestly if its at the point were your mad because people are doing it and killing you, maybe its because its a very tacticle advantage, when you change the way someone is use to shooting you it confuzzles you and you actualy have better acuracy laying down

When i started mw2 everyone use ump45 silenced and droppshotting and i got the D stain lol, then i changed my layout and learned to do it and boom im a pro haha, its also a big advantage for snipers to get that extra shot if they missed

The purpose of drop shooting is to clearly throw you off your shooting so that they obviously don't get killed. It's a specific person's way of playing so leave them be. You try practicing it and you can use it too... it's not a hack.

Drop shotting, is the single most annoying thing on call of duty.Ever.
