If you know your ranges of radar and hydro and you know what the enemy team has (which everyone does at the beginning of a match) and you are not changing how you play in reaction to those threats, then I hate to say it, but you gotta learn.
As a DD main, I have played quite a few battles even since the patch and still don't really have a problem.
Experience has taught me when to push, when to not and when radar'd, to COUNT so I know how long their radar is going to remain up.
Also, if people would focus the CRUISERS first, which lets be honest, SHOULD be the food for BBs currently because they are a huge threat, then everyone's lives get better in a battle.
Slow and steady, calculated placement and situational awareness can be VERY effective if you're a DD main.
