Yes, you are wrong.
You're asking for opinions, and opinions can't be neutral.
Saying that someone has to be part of the group that takes advantage of it is just a way to invalidate someone's opinion and make it fit better into your mindset.
In reality, my reasoning behind that is as follows:
The guards are at extremely risky spots. Not only that, they're at choke points surrounded by gate walls that any enemy player can just walk on and freely attack any guard farming groups without them retaliating at all.
Therefore, killing these NPCs is *extremely* risky, and balancing their values around having to DPS them for a reasonable amount of time and not just get obliterated within seconds is a logical consequence in my book and is a proper piece of enemy design.
Basically, it's a relatively short, but not unreasonably short, high-risk-high-reward fight that can get you killed very easily by other players. The NPCs are also very sensitive to movement and prone to resetting if the tank only gets pulled a few units away. They CC a lot and bait out many Remove Shock buffs, which makes the farming groups even more vulnerable.
Any higher health and attack values would result in another piece of dead content because nobody would even consider killing these mobs in the first place, and every option that you can call "not worth doing" is wasted potential gameplay in a game that's already relatively thin content wise.
So, there you go, a proper explanation as to why I think that the mob values are fitting in my opinion.
I'd like to return the question and ask you: What's your reasoning behind thinking that these mobs have too low values?
The only piece of info I can extract from your posts is "I don't like the color of their HP bars".
Looking forward to your reply.
