My situation is similar to you. I have been saving my steel for a long time, and as a DD main, I had high hope for Somers ever since they mentioned about this ship, because I really want a good steel DD.
This ship could have been either strong or fun, even both, but WG decided to make her a dud. As a result, I bought Bourgogne last night.
I have played this ship several times, and it felt great. I love the fast reload and fast speed.
I had my worry about future as well, such as the upcoming Slava and Hayate. If they are released with steel, I won't be able to afford them until next year around this time; however, I do not think that Hayate would be a steel ship. Releasing two T X Steel dds in half an year just seems unreal to me. Slava is OP at the moment, but even with her being OP, I still prefer a agile BB to a sniping BB.
My impression on WG about steel DDs: WG would never release an powerful steel DD, because DDs have the largest impact on the outcome of the game if you exclude CV. Placing an powerful ship that can decide the win or lose on the hands of a small group of super competitive players is not good game design.
