Well, you know Fabianh, I would say that the coef 5 rate is decorrelated with my number of unlocked items. That depends on the way you collect items (selective or not). If we look at my stats here, I am quite below my nominal coef 5 rate on the french server.
After more than 800 games there, I am normally around 1 coef 5 each 7.5 games (which is not a particularly lucky rate), knowing that in a usual game, I only go through PDs 3, 6, 11, 16, 92, and 97 which do not provide a lot of extra objects.
Here on the english server, I played only 46 games up to now and got 5 coef 5 items, which is less than 1 coef 5 each 9 games.

I don't feel particularly unlucky yet because the figures are still too low to make reliable stats, but it is really below the nominal rate I am used to.
Anyway, I was very surprised (and so happy

) to find 2 mandas almost successively. I just really hope that the game is not going to troll me by giving me all coef 5 items except the Book of Stars.
I wish you to find one manda soon.

Is it the only coef 5 you are missing ?
By the way, I am really impressed that you have had 3 aces of heart before 3 aces of diamonds, this is really exceptional and extremely lucky ! I've never seen an AoD in my game-life
Oh, and I do not found any coef 6 yet here, but I still have time since my usual rate is 1 each 200 games.
Sorry for the big block, I appreciate discussing items and figures related to them.
