Guess some people can't read sarcasm through words.
It won't be a gun added to the EC shop, olirus already said that long ago that no more EC items will be added (but you can't be so sure).
And why such a bias pricing? The reason why dual cost 25 EC more is because it's called dual sabre & has the ability to close/open. If that gun were to be priced at 125ec, then it shouldn't even cost one to be 100 and just let both be at the same equal pricing. Thus, it won't be considered 'op'.
