I had a report of 2 raid :
A 6hours raid --> 10 elemental water + some shitty stuff and 40k for 120k repair
A 8 hours raid --> nothing + some shitty stuff and 40k for 120k repair
Elemental water bonus on raid is OK in quantity (not what I expected but OK)
The problem is the frequency, no loot after 8 hours raid is a big timeloss. I hope it's just a bad luck
Other problem : people of my guild had problem with normal donjon : a lots of them had no tickets.
