I play a Warrior Priest currently in T1 and I'm always all over the objectives. Carrying the flags. Capping the points. Keeping people alive. Getting kills.
However, even in the scenario's that we win, Chaos has gotten more experience and renown by quite a bit.
I'll use this screencapture from a recent scenario as an example:

In this scenario (Shadowlands) I held the artifact for the entirety of the game **Yes, we won**. Obviously died, because of the ridiculous debuff, then went and picked it back up. I was primarily focusing on keeping myself alive, but was also saving team-members from death when necessary. I didn't do much damage, because once again, I was trying to stay alive with the artifact, however I managed to land 3 KB and particpate in 32 kills.
With the leading chaos player having 32 kills, 4 deaths, and 2 DBs.. They managed 11,177 experience and 2,435 renown.
Myself, being the leading order player having 34 kills, 2 deaths, and 3 DBs, and owning the objective the entire game got 8,977 exp and 1,928 renown.
Can someone please explain how this is calculated? This is T1 so it's not something like the potion of acclaim. It's even more annoying because a large portion of their team was rewarded more than myself, when I basically did most of the work as far as actually scoring us the win.
