All this open PvE fighting has brought up an interesting question, one that many people have some strong feelings on. What is the appropriate way to tag mobs? Is it okay to camp spawn points and AoE immediately in order to grab some scourge? Is it okay to take away another person's Shadow of Doom? What about if you accidently tag something you shouldn't have? Do you give them some gold in exchange?
I have to admit, after trying for over two hours to summon a Shadow of Doom and tag it, my group decided to go a different route. We went to a new spawn point, summoned all four, and threw out as much AoE as possible. Our thought was that doing this would mean we'd at least be able to get one Shadow (we ended up getting them all). This of course upset everyone else that was there – but we had tried for a while before hand to get a single one. And we did summon all the Shadows ourselves.
While this might be a questionable activity to some, it's what we did. But what would you do? How have you handled, and will you handle, tagging these mobs?
