Why don't we have deathwatch?

We started as deathwatch, with the most awesome skin of the game. Latter, we have only few itens that poorly resemble it.

1) Why don't we have the full set of deathwatch?

2) Why don't we have operation missions with the deathwatch, for example, we could have 2 missions with the map of the start of the game...

I hope devs see this...
