Dismissing complaints because the event was pushed back and will still be played is wrong and doesn't mean players weren't adversely affected by the delay. This is all about the time value of money (crystals in this case) and the notion that crystals today are always better than crystals tomorrow.
For exmaple: if the delayed crystals meant I couldn't refresh cantina enough to relic a character that is used on this weeks GC it will cost me the difference in rewards from the 8th crate to the 10th. The same is true for Assault Battles, Omega Battles, Special Events, etc. Once those are missed this week there is no way to ever get them back and there are often sizable differences in reward tiers.
