Note: this is all my opinion.
I am very tired of trench coats. I can only imagine that a TON of work went into the new armor. However, to me it looks like a blend of bladed armor and norn, cultural armor. Take a look at that gw2style page. Medium, armor-class people go out of their way to find combos that aren’t trench coats. I’ve been playing this game long enough that I have 3 combos of armor already built and this seems like a waste of time and money.
