So I just started playing Gems of War 2 days ago. Obviously, I don't meet your requirements.
But... in 2 days I am already Level 34, PVP Tier 1 (Rank 8,831), I've contributed 11,000 to my current guild which I'd randomly joined, I already have my 1,500 weekly Guild Seals, and I have 124 trophies. Hoping you can see the potential here. I only have about 3,000 gold, and I'm still in the process of opening the various kingdoms (have opened 22 so far).
If you're not interested, no worries and I'll continue looking.
