Here's a really mad idea. How about the prize stats listed as part of the reward for completing an event actually *match* the stats on the item you receive!! As an added bonus, (just thinking outside the box, now) if you complete an event you actually *receive* the prize! No delays, no dodgy word salads about how "it is known," that the "intended results," will be released "at a future time."
Just an old fashion cause and effect relationship where you finishing the event causes the reward to be issued as advertised, and at the moment you are done!
Wacky stuff, kids!
