man...game looks really good... but wanna hold off because of Borderlands 2...
may pick it up still....if i can find a physical copy.
B2 will be fantastic (i'm hoping) but it also won't have the longevity of GW2. It is really great. There are a few beefs I have with it - it can feel a bit grind-y and repetitive at times - which is to be expected when you unlock all available slots by 30 - so really the next 50 levels is just traits and other skills you more than likely won't be using that much if you've chosen worthwhile ones ahead of time for your playstyle and decide not to change them out.
DEs are fun but can devolve into utter chaos with tons of people - which, for me, lessens the experience due to the skill floor at that point being non-existent.
Dungeons are great, exploration is there if you are into that sort of thing, plenty of achievements to hunt, crafting is pretty par-for-the-course except for discovery (which IMO should be the only way to craft, personal preference), PvP so far for me has been fun. A bit too much Zerg in WvW but if you roll off the beaten path with a small group it gets hella fun sneaking into enemy territory and stealing bases/supplies - so I stay away from all out AOE fest zergs. sPvP seems great except there could be a few balance tweaks(?) - I haven't studied up on proper sPvP builds so I take my own comment with a grain of salt since I need to work on a proper build and actually practice for a while. It seems like it is on the right track for being so early on in its release.
Plenty of fun to be had - but you will have a tough choice with your main character tho - they are all very fun to play - some more straight forward than others (which could be why I feel things get grind-y and repetitive at times) - but if that is the case - you can always play on another toon. I will probably break from my Warrior this week and concentrate on my Ranger. I like both bow styles and they have an excellent array of melee options even though they are (technically) a ranged class.
You will enjoy it. There ARE hiccups this early on since it is an MMO - so it would be understandable if you feel the product is slightly "incomplete" at this time. It's all a matter of personal preference on how you view those hiccups.
6 months from now will paint a much better picture of the game as I feel there is a lot of ironing that needs to be done to a few basic and more complex systems of the game - but it is not in a broken state so I'm OK with that.
I say get it if you can - even if you don't like the release period of new MMOs - you can always come back a few months from now when I'm sure the experience will be far smoother than it is now.
