Rewards?

Does anyone know what the rewards are for this, if any?

Titles.

The rewards are the 3 titles: "The Scoring Master", "The Stealing Master", and "The Defense Master" title. I wonder if these titles count as "master" titles for the 10 and 20 Master Title Achievements?

They do not. If they did, I'd have the 10 title achievement with an additional 2 titles towards the 20 achievement.

They don't seem to be helping me any.

I got the stealing master title with only 10 steal points

I think it's funny how people wrote to obtain the titles this year completely differently than last year. There was a giant discussion last year to figure out exactly how it was done, and people ignored that entirely and tried to figure it out anew this year.

The Scoring Master is correct.

The Stealing Master is wrong. The actual requirements are to be in the top three on your team and return the most of your own flag. This is only give one per game, not per team. So if someone returns more flags from their own team than you do, but aren't in the top three, no one is given the title for the round. (It may possibly be top 5, however.)

And for defending master, you need to be first place on your team, and you have to kill the most. You can turn in any flag at all.

You can get all three titles with ONLY turning in your own teams flag. So just stalk your flag and kill people when they take one, then turn it back in.
