Leave 3 single champs in defense for the week. Friday or Saturday switch to a real defense.

Hi, thanks, so basically the power of your def determins the quality of your enemies. Which may explain why I keep getting the same rotation of players more or less. Will try that next week and see how it goes. 

NO, your current score determines your match-ups.

Most people tend to do weak 1-man defenses the first several days in the rotation, to get easier offense match-ups to fight against, and then switch to a tougher defense in the last couple days to keep from losing points on defense

So basically I could go skip, skip, skip in all my battles mon - fri and just play it sat and sun to to get and keep myself green. As a rule my def is attacked very rarely. It's just I find tag arena so tedious, each battle lasts forever for no real rewards. Worst part of an otherwise enjoyable game. If it wasn't for this mission, I wouldn't even bother. 

This is because almost everyone is doing whats posted above, so no you wouldnt be getting attacked until the weekend.

Everyone is is fighting one man defense teams all week.

Wait'll you get to the "reach Gold 1 in Tag team"

Worst mission in the game.

But it feels SO amazing to get it done and then just not care at all about tag team ever again
