I have over 16 incomplete fragment stacks. Most items purchased via numerous event rolls, a couple from event rewards. Five of these can not be completed as the Event fragments where changed without notice and poof gone. Two of them are from special events and 1 of those has never been offered again, the other was some outlandish amounts required to gain. I look at each event fragment as costing 880 rubies as this is the required cost of 10 spins within the event to obtain a guaranteed fragment. This last special event <Valentine's> I purchased 8 sword fragments from the shop figuring I would receive the other 2 fragments needed for a completed item. After spending well over 6,000 rubies on attempts in the Goddess that was suppose to drop this said sword fragment, received NONE. Now I have 8 fragments of an item that I can not complete. To me this is close to being a situation where BUYER BEWARE. Unspoken changes, superfluous ruby requirements for opportunity to spend real $$ just to get a low level item to complete a set. Please, fix this problem. Am certain I am not alone in suffering with this problem. I reported the situation concerning the sword within the Valentine's Event and response was event was functioning as intended. Well am sure it was! lol Take my $$ and have random drop ratio so high its most difficult to obtain even 1 drop.
