Player Opinion
Battleship - Mutsu BPros:
- Largest guns of her tier, which can overmatch the bow armor of all her standard competition.
- Has a fairly high top-speed; can outrun most equal and lower tier battleships.
- Large HP pool.
- Better-than-average secondary battery range.
Cons:
- Reasonably well protected on the bow of the ship but terrible armor along her flanks and rear means she will be citadeled very easily if over extended.
- Larger-than-average turning circle radius for a Tier V battleship.
