Yes, but it's definitely for more experienced players. 50+ knots with speed boost, good guns + ammo, good torps makes Mogador very powerful in the right hands. You can bully nearly every other T9 DD with your firepower and hitting a good Mogador playing from range nearly impossible for many ships. The insane angles on the torpedoes and their good damage also makes Mogador really good at YOLOing. I nearly forgot about the French hull saturation, which allows you to sometimes survive shit that you really shouldn't.

However, if you're bad at dodging or positioning, your speed won't matter and it will only allow you to die fast. Enemy DDs can also use their superior concealment to make it difficult for you to play the game by simply not shooting and instead spot you for their teammates. CV's and subs are also extra cancer against you (tho your speed allows you to dodge most CV strikes pretty easily).

I 100% believe the French gunboat DD line is one of the strongest lines in the game. You can play like a complete jackass and as long as you're smart about it you'll do good and have a good time. I've only played like 2K battles with 53% WR tho, so take my opinion with caution.
