The only logical point in this is 3. All the others are opinions based on your experiences, not the majority. The problem is not Thorn, the problem is Bungie not running a wannabe MMO like they should be. Look at any popular MMO and you'll see how often things get nerfed/buffed for balance (hint: it's not in the single digits per year). As a pretty much pvp only player (I did my first raid about a month ago), it's blatantly obvious that Bungie could care less about balance and are just trying to keep the audience they have interested in semi-new content.
