There's a major concern when using diamonds in this event for the HoH. You get 1 L1 HoH during the quest line and then you only get 1 L1 HoH for every full cycle of grand prizes. You get 3 upgrade kits from the quests, and there are 8 upgrade kits in each full cycle of Grand Prizes. It takes 1 L1 HoH and 6 upgrade kits for every maxxed out building. That means when the event is over, if you've spent diamonds, you're going to have enough upgrade kits to level another HoH without having the ability to get another L1 HoH. And it get's worse the more HoH's you build. So if you have 8 HoH's built, you're going to have 12 upgrade kits (enough for two more HoH's) by the end of the event, and no way to get L1 HoH's as the quest kits don't give the option for both. Am I missing something or are those of us who spent diamonds on this event left in a situation where we have more upgrade kits than is possible to build main buildings?
