Player Opinion

Pros:

• Good HE damage, penetration and fire chance
• High damage potential per salvo due thanks to the high number of guns
• Access to the Smoke Generator, which is uncommon for a Pan-European destroyer, and an improved version of the Defensive AA Fireconsumable

Cons:

• No access to AP shells
• Weak torpedoes with short range and low damage; they do not have any improvement over Stord's
• Weaker version of the Engine Boostconsumable with only a 5% bonus instead of the standard 8%
