This morning I am seeing this in my Team Clash:
This looks remarkably like the kind of rewards bonuses we see for all other events.
This to me suggests that the app is trying to reach individual players within teams, to try encourage us to play more levels to gain individual rewards not directly connected with the team effort, which essentially makes it a single player event.
I have also noted that the teams the app picks for me to compete with are remarkably similar to my own team:
My team has six players and only one of them has been active at all since the beginning of the week. When looking at the player cards in the opposition teams these are also teams with 5 or 6 members, of whom only one is active. This makes this event similar to single player leaderboard events, and is just masquerading as a team feature.
Don't get me wrong: I do love this feature as putting all my accounts into one team helps me gain control over it, which is perfect for me. But it now seems to be just an illusion like the rest of the game.
There also seems to be an issue with it not working properly as there are countless teams with inactive members including those who set up the teams. So those teams are now like zombies.
Anyone who is part of an inactive team should leave that team and look for a better one.
