I do agree with you on some topics. The game definately got more boring and there are a lot of quests lagging to get players to actually be online and play the game. Drops, adena in game rewards are now horrible.
But there is nothing wrong with the new added instances. Except epics are somewhat much too difficult since most players aren't quite to that level of strength yet.
Getting gear below R-grade would be absolutely useless right I shouldn't have to explain why.
I agree that Kartia should get revamped. Dim crack and rift never should of been revolved.
But lastly, I agree strongly with the new automated hunting system. I agree that it sucks to macro all the time but not everyone has 10 hrs a day to sit in front of their pc's to kill mobs all day to make .5% xp. That would be a lot worse the leaving your char xp in macro.
At least busy working people can keep up in level with the people that don't work.
