Honestly aigle is one of the best dd hunter.
Ppl are over estimating concealment.
As a gunboat you primary role is to draw attention on you.
The french dd line will surely be the fastest of all. You can 't give everything to a line like this.
It' s always the same thing on each line or you adapt to the weakness of the line or you will not play them cause you can' t adapt your playstyle. (For me it s american cruiser to much boring)
But honestly the ship haven't reach a test phase yet, so wait and see
