It seems the only items in the loot tables are the items that have been reworked with the new update all of the older style effects and unique special effects are missing from the tables severely limiting the amount of random loot possibilities.
Another issue is quest rewards based on class. As an WF artificer I would receive a selection of a handful of crossbows and docents as an end reward for a quest prior to update 19. Now however, I have only been able to pull 2 repeaters from end rewards out of the 75-100 quests I've ran. perhaps this is tied in with the 20th raid completion list problem.
on a side note there is also a problem with Artificer enhancement Infused Armor core ability. It does not grant 10 PR nor 20% arcane spell failure. unless there is a hidden issue with stacking that I cannot detect.
