When I looked at those times I thought great, 3x daily to AMS at times broadly similar to KL's regional services, they must have an interline agreement and this could actually work.
Then I saw the evening flight wasn't to AMS, it was a second daily DUB. Then I found out it all starts in just two weeks and my heart sank.
This clearly won't work, DUB doesn't need 2x daily especially when the times aren't great for a business day return. The second AMS is too early, so not much use for business either, though could be redeemed if connections are possible.
I would keep the morning AMS, perhaps keep the morning DUB, then EDI in the afternoon followed by AMS in the evening. Even then it's a gamble.
At least Cityjet has marginally greater brand awareness than Darwin!
