Rep and PvP

[Lorddundar]

As you kill you gain reputation. This gain seems to be directly related to how many people are on your team. Example when I did my first solo kill awhile back I gained 1 rep. A few nights ago I joined up with a stalker and we whacked a guy a couple of times. Each time we killed him we only gained .5 rep. Over the course of a couple of days my rep has slow gone down to 0 again.
So what does this mean?
To get the PvP badges for killing other players you need to gain a rep of 100, 200, and 400. The first time your rep reaches the aforementioned levels you will gain a badge. So to gain a badge you will need to kill solo at least 100 people but in a group of 4 you will need to kill 400 (sucky) as there are very few hero running around in Bloody Bay it is hard to reach the required rep to get the badge. I think that base raids are where its at.
