In my opinion. If beta didnt have CMS, or we had it, I couldnt say anything bad about this event. I dont like the main price (so much), but it is a neccesary building to keep the balance. Sometimes it´s a defence booster... off booster... now goods.... so ok.
But yes, all the event will have the CMS shadow, which will cover everything. Could I be happy with 20 carousels?, ofc. But I would shot my brain off if them CMS is released. And, at the end, we never know. Because, in my opinión, releasing the CMS the last day to make people to spend money in scrolls, is more sensible than not release the CMS and make people angry. Call me madman, but i really think that.
They could say something at the beginning: "the info you have is wrong, this event will be a different one". Directly. But instead of that, i remember the "I hope you get it soon" (or something like that).
