This event is looking below average compared to others this year.
I look at todays prizes (9/12/16) and only the daily special (Reno kit) is worthwhile. mot of the rest are small packs of coins etc, a standard, not premium, cultural building, or forge point packs, which can be won everyday from recurring quests. The rest are stars/shuffle..event related prizes, which are pointless if the other prizes are dismal.
So, for my 24 stars earnt today from daily reset and quest, I have 2 chances in 18 to hit the reno kit, made even less likely if i get a shuffle.
it barely seems worth it for those odds.
I spent 700 diamonds a couple days ago for the SoK daily special, and had 80 stars saved, giving me 180 stars to try with. 18 presents to choose from, 180 stars, I should get at least one SoK, right? 18 shots, and 3 shuffles later, I have coins, supplies, and a rogue...feeling ripped off, and not buying more diamonds for this rubbish.
