also Just want to throw my opinions on the event out there now I've had a chance to play it for a day. In general i like it. It has a cool concept and introduces pets which is a nice touch.
I have only one main issue with it. why is the task reset 4 hours and area resets 8 hours. seeing as it often takes 2-3 runs of an area to complete a task you essentially HAVE to spend shardium to complete the tasks quickly enough to get the pets by the end of the event. Yes you can get the reset fish things for 5 tokens but you need those tokens to get the pets. basically the area reset cooldown needs to be smaller, without using area resets it would take 16hours to complete one round of quests.

I have all areas unlocked, and I haven't had issues completing the quests because i've been using some shardium to catch up today as I missed the first 3 days of the event. I agree that the general collection quests are easily completable twice in 8 hours by using each area once. my issue has been with the specific drop quests. for these you have to reset to complete it in the 4 hour time till it could be reset. and when you reset it the 8 hour timer restarts effectively meaning that I haven't used it at all. my suggestion would be to make the timer give you a free reset of each area every 8 hours regardless of paid resets, because at the moment it just feels redundant.

Also could a note be added to the pets in the shop to say what stat they improve? because players will favor a specific stat and as you say it is unlikely that players will get them all so it would suck if you get one with a stat you don't want.

EDIT: some of the specific collections (skelly skulls and goblin fragments) can take far more resets to complete, sometimes 6-7 resets.

Ah ok, have you been leveling up, and as such is your gear lvl keeping up with your lvl? There have been a lot of less than max lvl players who have been finding the event tough too.

OK ... that helps but I spent over 2k shardium to bring the blacksmith to 1 lvl below mine and i didn't have enough money to enchant even 2 items to full. I only had that shardium as I had put real money into the game, else no hope.
