I personally dislike the agro indicator, takes away from my enjoyment of exploring. I still think I am one of few people who know Efts Agro to sound and if you stop moving they wont actually agro you unless you run into them. The monsters have so many unique quirks built into them.

From the above mentioned Efts method of actually agroing you. "if you stop moving when they pick up there head and look a you they will go back to being non-agressive and then you can easilly run by or use your DoL skills almost next to them.

To funguars poison cloud only being released if you hit them when they are puffed up, all sorts of things that people don't apreciate in the long run it seems.

If anything I would at least want the option to turn it off because I find the icon super annoying.
