As for the feedback - I love this type of event
About the main price - well, I don't have space even for buildings from the previous two events. I Don't want to progress in eras and all diamond spaces available I have already purchased. So no, I won't probably building it for this reason. And even if I'd like to see better or different stats, I understand that can't get what I "want" in every event. I love getting ATT boosts myself, but I personally know several players who simply don't attack, period. So they have no use for ATT buildings and I believe they are still legitimate players of this game. So it is only fair that not every event has something for the attackers (just my 2 cents...).
The event itself (unlike some other events) is awesome. Thank you.
