Thank you so much ^^
Well, years trading Tinsels, I never got near a 2nd gen. I have enough Tinsels, and the last time I tried to trade the lowest gens I have(I always ask for a fair trade, which means a same gen swap), I end up with the Tinsels growing up in my scroll and no offers. So I'm not into them right now.
The problem is that for you to produce 3rd gens, it means that you have to own 2nd gens to breed. I never got any with Tinsels, so I would wish to have at least one 2nd gen Shimmer.
The lowest gens I have are a 3rd gen male and female(here's the lineage of one of their offspring: http://dragcave.net/lineage/iMk4E), and as they are even gen, I never get a stairstep swap for example. I am happy with longer gens, but the problem is that they just don't trade. Having a 2nd gen will solve this years long issue I have since Tinsels, that's all
I will keep trying and hope that I can get fair offers for my CB green Copper.
