There seems to be a number of skills on NPC’s that aren’t actually mentioned at all underneath the name of an NPC when you target it.
If you’re going to give players insights into what an NPC does, then I think it needs to be comprehensive yet concise.
For instance, it’s no use telling players that a boss only has a knockdown, when he also does an AOE immediately after that.
Now, from a certain point of view I’m sure someone would say that it’s part of the “fun” finding out. But, listing npc skills under the target name does not follow that mindset.
If you’re going to do something, do it right. If necessary, put the list of skills and abilities on an option on the target portrait right-click menu if necessary. Just ensure that it’s comprehensive.
