Counterpoint: Don't do it is perfectly valid. There are a couple of reasons I believe this. 1) this is a mobile game. There is a ton to do, even at end game, that doesn't require completing GW every day. Or at all. 2) people may have to completely stop making progress in other areas to farm Resistance, or another team, for GW. This may be a temporary "don't do it."
The best compromise in both situations is to simply run it on auto and reset when you have no teams left. You won't get all 1600 tokens but you should get 600 to 800.
There is nothing that says you have to do everything all the time. In fact, in a game like this that is nearly impossible until end game.
Not trying to argue. Just offering a different point of view.
