Well, I think it's certainly worth playing brawls if you're already in a guild and helped with the years of struggle and work to get to the top tiers. Once there, it's not a lot of effort to enter your brawl teams and earn some small rewards.

On the other hand, are guild brawls getting boring and need care and attention? Absolutely. Fortunately, Dave has said on The People's Guild podcast that guild updates are on the radar and will be getting attention. Nice to know the team hasn't forgotten about guilds at least.
