Good point, we are in a similar situation as a few of us can get 3-6m each and the rest can just do whatever to get the 22m rewards.
I'm sure the gap is deliberate meaning to bridge that it needs more investment across the board, although arguably for our 380m guild getting 1m plus out of the other 45 guild members should be fairly easy but then we have the RNG element that can make this hard if you aren't prepared to retry, and I fully appreciate why many don't.
Someone at CG has tuned this perfectly, its almost admirable.
