I think that some brawls are quite easy and some others can be really difficult. I think generally, a lot of people are no longer interested in filling their fray, maybe it's the general feeling of the Crypto market, I don't really know. But, decent wins there.
Yea, but I still think brawls are more rewarding compared to the ranked battles. It might not be the case if people are in Diamond and above, but most of my guild isn't in the league.

Diamond league is an expensive place to actually be in. So if a person can afford to meet with the requirements of playing there. I guess they'll choose bigger guilds to play for.
