Speaking of melees... does anyone ever bother with them? I feel like I'm giving a friendly pat on the back whenever I use them. They're useless.
Melee can maximize your damage output in close quarters and when fighting over points. You can weave it in between reloads or even try to save part of a clip depending on who you are playing. It's not a lot, but sometimes that little extra can mean an elimination for you rather than OF you. I die to a decent amount of folks who have less than 20 health and realize I was not using melee to fill the gaps between abilities and clips.
I play PC and have mapped it to middle mouse click. Feels good there.
