Questions about Achievements

I have 2 questions about achievements:
1. About Ranked S&D achievement. It says I need 1700 score but that's Gold 1 or 2 right? I did the 10 matches for placement, got into Silver 6, had 1577 points. Lost a few games points got down to like 1560 or so, then win a few game and got back to 1577. Can someone explain how this Achievement works? I need to get to Gold 1 or 2 (I think that's for like 1700 points). Or they stack somehow, or atleast they stack over the seasons?

2. About "Base Struggle Combat". That was a mode just for a period or something, like "Sheep Mode"? Or what's the game for that Achievement.
