Cruisers, or CA/CL (CA for Cruiser Armoured and CL for Cruiser Light), are the most versatile ship class in World of Warships Blitz. Their fast firing, accurate guns make them perfect for anti-destroyer screening, their anti-air capabilities will help immensely dealing with planes and their good maneuverability, speed and, on some cruisers, torpedoes allow them to adapt to any battle scenario and to tackle even the biggest adversaries.
The flipside of this versatility is that cruisers are the jack-of-all-trades, master-of-none class and there will always be other, more specialized ships that will be faster, better armed or have more protection. This is why it is the job of a good cruiser commander to watch the flow of battle and adapt to the circumstances as they unfold.
