So not long after posting here that I would not be playing GW2 until they added a dungeon finder I find myself playing it. I bought it simply because a friend bought it and I wanted to join him. In this case friendship is more important to me than principle.
So what do I think?
It's a great game to start off with. All the recent games of this style have had fantastic initial experiences - Rift, SWTOR and so on plus GW2 are miles more interesting and engaging than games we played 10 or 20 years ago.
Whether it will have tenacity is open to question. I do really feel that a lack of a LFD tool hurts it. Having played I can see that moving to the dungeon is a non-issue, they have teleporters at them. We'll see.
The WvWvW currently seems broken but I'm sure that will improve when they stop allowing migration to the winning servers.
PvP I haven't tried yet but I'm sure it will be really well done. It was superb in GW1.
The game is very alt friendly with interesting and complex build trees. For players like me who enjoy searching for powerful combinations there's a lot to wrap our heads around and theorycraft with. Plus the exploration driven maps are possibly more fun to alt on than quest driven maps are.
I suspect that the game will need to develop a stronger end game pve experience to really keep a good population though. I don't think farming noobs in battlegrounds is a sustainable end game and it also doesn't seem like there's enough PvE content to accommodate a genuine pve end game.
For all that there's certainly enough to occupy me for months and I'll have this game on my desktop for years. I've been having a blast so far with my Warrior and am looking forward to leveling all of the character classes eventually.
