Well, argument about how many unique dungeons there were or weren't aside, I do agree that the copy and paste delves are a bit...meh. I have no issue with it on the whole, and I do see it more as a way of adding extra 'dungeon crawl' areas as a bonus rather than lazy design - there are lots of unique dungeons and the fact that there are lots of copy and paste areas doesn't really detract from that, the only problem is sometimes it gives you the impression that it is all the same.
Regarding grind quests, I am reluctant to have them added to the game as it encourages devs to start getting lazy. I like the questing in this game and like the fact the quests take you to VR 10. There is no harm in being able to grind to the top if that is your playstyle, and VR lvls need an improvement in that area (but 1.1 is doubling xp so maybe that will help) as 1-50 seems fine. Just like I do not want to be forced to grind to VR 10, I don't think it is right to be forced to quest, some people aren't huge fans of quests, heck even those that are can be burnt out by VR ranks. While I know there is the arguement of 'why play ESO if you don't like questing' well, even questing aside the game is very good, the combat is fun and the mechanics interesting, for those that like questing it makes it an excellent game, for those that don't, it is still a good game.
