Last GC I bought the 3 50c refreshes both days, and finished near the end of sector 4, I picked up 8 RC shards during the event, and still added like 1k currency to my bank. I do not see the need to have my crystals restored, I got benefit from spending them. If you spent a large number of crystals before the cancellation was announced, I can see why you would really want to have them reimbursed.
What bothers me are the players that took advantage of the situation to finish all sectors buy spending a huge amount of crystals... The would end up benefiting from the extra event currency at no cost.
If you spent 3k crystals and all your event currency the last day to blitz sector 5, because there was a post saying they "might" be reimbursed... I have little sympathy if your not.
