I will start off by saying that this post is intended to be positive, and in no way an excuse for all and sundry to vent their wrath in reply.
I, like the next player, am always glad to see new content, new events and new challenges, but spending (too long) a career working on projects has taught me well that taking on too much change all at once will only lead to disappointment and difficulty.
I cannot help thinking that much of the frustration felt by players in the recent event(s) has come about not because of any lack of competence on the part of the Game Developers, but as a result of trying too much, too quickly, under too much pressure to deliver.
With that in mind, my "suggestion" would be for a show of hands from players to give "feedback" on what we would all like. Do we want:
a) Lots more new content
b) A period of peace, quiet and stabilisation between Easter and Halloween to get the game on a stable footing before future events?
Both would be great, but you don't always get what you want.
In the interim, there are always the well-tried mini-events (Pirate Week, Co-Op week etc) if it is felt necessary to "stimulate" players during the Summer months. There seems to be quite a bit of new content (Endless Coal and Gold Mines etc) to keep many players (not all I admit) occupied for a while, and plenty to spend gems on if you are that way inclined whilst items get remedied.
I vote b.
