What is the Scenario Experience Points Mechanic?

[taultbobby]

I've been playing this for a couple of months now, and I've realised that Scenarios are the best way to exp ... providing you win!

However, I have noticed a trend which I cannot seem to work out at, which is the amount of exp you get from the scenarios, and what causes the different amounts.

I know that the basic formula is "More Scenario points = more experience points". Therefore, a 500 point win will net you a lot of point, but so will a 480 point loss.

Now, what is confusing me is that even on winning teams there seems to be a large amount of difference between exp gained, and I can't figure it out! I have several characters as I'm still finding my way, so I rotate in between those with rested xp to maximise levelling. Thus, even with Max XP bonus, I can win and still be bottom of the team's XP gain.

Deathblows, Kills, Healing, Damage Done ... all of these equally do NOT seem to affect the xp. As I have ranked top in all of these at different times, and still not had most xp. I thought it might be "Do the mechanic of the SC" e.g. flag capping, flag holding, flag running, etc. yet that also doesn't seem to do it.

So... i'm at a loss! What is the mechanic that will allow you to get the most exp per scenario?
