My guild has just levelled up to 38. With only 17 members it took us months to accumulate the 1.2 billion required so when we eventually managed to get there it was extremely disappointing to get absolutely zero reward for doing so except to be told we must save another 1.8 billion to level up again.
After all that hard work it wouldn't hurt Playmage to give some small reward would it? Surely there should be something for every level up?
