There are no active admins on official servers, there’s just too many servers to keep staff on all of them, and stuff can get out of hand. Private servers with active admins are the best if you are worried about offline raiding and griefing. I have played on several private servers and the admins (in my experience) have all been fair and non abusive.
Archery is good for catching someone off guard at a considerable range if you dump all of your stats into it (and they’re not wearing heavy armor/shield), but it is primarily a melee game. All of the weapons are very unique with different fighting styles and techniques to get the most out of them. I would say they have all of the weapons working at a good balance now, aside from maces (which are too short on range to be effective). This new combat system was the deciding factor for me to finally buy the game, and it did not disappoint. It is very unique for a survival game and fits the Conan world very well.
There is no taming mounts like Ark yet (it may come in a few months after launch). There is however slaves! You can knock out npc’s and drag them to a wheel of pain to break them and make 'em work for you. World bosses and dungeons are far easier if you have a few teammates to assist you, but they can be done solo (although that may take some time).
Knowing that wipes are coming for launch in a week, many people have quit for the time being. Private servers that do not wipe run the risk of old bugs returning from old items that will be recoded during the launch patch (gas orbs and sandstone ceilings for instance). There are still some bugs from the testlive combat patches that still need fixed in live, and other things (like rock nodes) are still not bug free. I have been spending time recently building structures and perfecting the designs for when i finally try to implement them after launch. Hope you give the game a try and enjoy!
