Hames orc overlord UD abuse

[EyloghtoC 6]

At a recent communication with admin we disagreed regarding a skill of a monster.
Can someone help me persuade our BELOVED admin to change his mind and do his job?

The monster is Hames orc overlord of Blazing swamp area.
This monster spamm nonstop until it runs out of mp Ultimate Defense.
Admin claims its a self buff and it should cast.

WE ALL KNOW THAT UD ON MOBS IS A SKILL USED PRIOR THEIR DEATH MEANING WHEN HAS LOW HP OR AT LEAST WHEN HIT.
THIS MOB SPAMMS UD ALL THE TIME. 
Can some1 provide links or some logic on how skills work and solve this issue?

Now people dont seem to get interested or worry, but i ask the community how to get 450 Moonstone shards per char when they do sub? How you gonna farm it?
And i remember on all interlude servers i have been it never was like this. 
To be honest i dont remember on official as it has been a long time since then but for jesus christ this is not normal behaviour. 
Edit this mob to be NORMAL
