As PvP isn't very popular in this game, I predict feast will get a pretty similar fate as wd (hopefully to a lesser extend). It's popularity will at least dwindle over time.

A few concerns:

1) If I understand this correctly, you have to win 3/5 matches when fighting for promotion to advance in rank? Reaching diamond rank seems impossible to me if the mode loses interest.

2) The same players will -after a while (weeks, months)- be at the top, season after season, due to fewer participants.

3) People like me, who don't care about rank or reward, will most likely only play the 8vs8 "for fun" mode if the drama gets too high. I like to bring my popcorn to FL sometimes, but in feast mode the potential level of prestige at stake is not something some random pugs are willing to deal with if the drama gets too tense; losing even more players.

4) Have SE done anything to prevent match fixing? The 3/5 promotional thing seems good and all, but aren't there other ways to exploit the system?
