If I remember correctly, there was a crystal storm event planned to compensate the daily login rewards. If they are already giving crystals for playing the game, how about adding 4 quests in that event. The reward can be gold (let's say 1000) if the number of your crystals that you already have is a multiple of 5. If it's not, you get a single crystal. 4 quests mean max 4 crystals so that everyone can round up their amount of crystals to a multiple of 5. If someone requires only 1 crystal to round up, they will get gold for rest of the quests because of the above logic (i guess so...).

I want to round up the value not only because lack of 2 crystals bothers me, but also because it renders the rest of my 98 crystals useless in getting something. Or sometimes 48 crystals are useless. In a crystal storm event, they usually give away 60-120 crystals in a weekend. 4 more probably won't do much harm.

PS: please don't tell me i missed the crystal storm event... I kinda lost track of whats happening here.

Edit: Typo.
