Packet Sniffing for XP

Hey. I've used WPE Pro before, but not for Tribes. I understand that the Packets used to request XP at the end of a match aren't encrypted, and that they can be re-sent for extra XP. However, there are a lot of packets to sift through whenever I listen (like 100/s) and I don't know what to search for/edit. Can anyone help me?

Also, when I redeemed a promotion code for gold, it looked as though I received the gold without sending or receiving any packets. How is this possible?

You cant do it. When a packet is sent its from there server v.v ffs that one guy who was bull shitting is a fucking idiot. What does server sided mean if it's not server sided lolol
