[Armitee]

Has anyone noticed how you cant loot some mobs, i just killed Hezrul for his quest in the barrens and he didnt drop his head, not even that, i could not loot his corpse, please fix

Actually quite likely that it's due to your WDB and/or WTF imho.

Can you tell me his spawn coordinates? Sick of searching

[Ragstal]

i agree and absolute hating that fact that there are still monsters that do not drop loot even some copper for example i also hate that they drop so little materials would not be nicer to have more often monster spawning and droping more loot for example u kill a boar and drops 2 meats 5 copper and 2 tusks 1 minor healing pot etc something like those not op things but anything low more often in bigger quantity to enjoy it more we sure need way more monsters and quicker spawn and for sure not aggressive ones close to one another and not many of those in like 5-9 hostile really close to take agro from them

If you check the latest Patch notes you will understand why this happens. I'll highlight the most important bits, and you can check here for the original post with the patch notes.

PERFORMANCE AND LAGS:
During this week, we applied a second bunch of fixes to reduce the lag / delay, after the dynamic lag reduction system last week.
We also implemented an index to know how our players feel the lag. The lower it is, the less our players feel the lag. It was around 500 at the beginning of the week, and it has been lowered thanks to the different fixes to less than 400 (ie 20% lag reduction, for a similar number of online players). Note that this index also counts client connection lags, not related to the server.

How does it work ?
Several strategies have been implemented.
First, we assigned different priorities to the different tasks the server has to do:
Spells and movement server: top priority
Chat server: medium priority
Creatures/pets AI: medium priority
Items/AH server: low priority
Characters loading and mail server: lowest priority

That's why when sending and mail to another character it can take a big while for it to be recieved in the other end. (as the mailling system is in the lowest priority)

I'll quote again the patch notes on what is being done about it in the future and probably a better explanation than mine.

It means that you may experience a delay when sending mails, looting items, ... But it is only to allow a real-time handling of the spells, our top priority. So do not rely on the chat to test if the server lags for example

Our second strategy is to define a priority between the players. Someone being in combat, casting spells, or in a dungeon / battleground will have a higher priority than a player that is AFK in a capital, playing with the AH, or simply chatting.

Hope it clarified this issue, and even if it doesn't resolves the problem, atleast you know why (and maybe how to avoid it)

Good luck in your questing, and I hope I was of some assistance.
