Struggling for Silver League

As I finally got my first Level 2 Summoner (as you see in my last post) I set my goal to reach Silver I. That means I need to reach a rating of at least 1600. Now I see that I am already struggling to get to even Silver III. I have now fought a few battles but am staying at around 900 for around 10-15 battles.

At least I managed to finish 2 daily quests, and I hope now that I don't have to worry about that I will really start through. I am not giving up yet, but I realized now that this will be harder than I thought!
