I think it might just be a weird way of wording for them, probably maintenance being a pause of events for a few days, while they work out some changes. That's what I'm hoping for at least.
If that's the case, here's some suggestions-
-Eradicate the crazy and unfinishable goals for CWA and especially Space Age players
-Come up with something new for second and fourth rewards, no more food and gold... maybe for players up to iron or classical age this is an okay reward, not anybody else. Nobody wants to do tens or hundreds of matches for the worth of 1 raiding.
-No more speed up usage events!! Absolutely nobody likes this.
-Give us some legendary war artifacts to achieve from time to time. My museum is still empty there. This is really no good business model you're running there with the museum - if you let players experience some good free legendaries from time to time, it is more likely some will end up buying some from time to time as well. The same teasing model which I'm sure you're running already with the event building and TT rewards.
