Seriously this seems like a no brainer. Everyone says that aquaman is useless outside of the ocean, which is kinda true cause the only thing he brings to the table is controlling fish which requires large bodies of water(cause one goldfish ain't gonna do jack). If he had hydrokinesis he would have some use cause
1. There is water in the air so he always has access to it
2. It's a no brainer
He could be walking down mainstreet and he see some bank robbers and then he looks at a fire hydrant and the top comes off and then he uses the water to stop the crooks. Pretty basic stuff.
Someone tell me why??????
