I am an old time player of MMOs. I have played WoW the most, and SWG before that. I have also played most other MMOs in search of a better one.
I bought GW2 pre-release and played a while until level 14 maybe before I gave it up in boredom. Why boredom?
Things I did not like were:
I had no clear motives, I was "drifting on the map" without a semi-clear understanding of what I was trying to achieve or what an extra level might offer me. Quests were kind of haphazard and random. I was seriously missing rewards, targets.
WoW offers well defined, achievable, very rewarding targets for the new players.
WoW has huge maps which you can explore in every direction and where you can travel on foot, or on mount, you can fly or swim. A totally linear 3D world to explore. Each of the main areas of WoW are as big as other "MMO's" maps put together. If you are an explorer and like to level up doing quests WoW is very rewarding. And as you level up you get travel forms, mounts, flying mounts, making exploration all the better. You have also taxis that fly you over land, boats to take you over water, you have to quest on little islands, or near the shores, or near mountainous areas, desolate lans, volcanoes. Lots of variety.
Even if you are not exploring much, mounts is the greatest reward as you are levelling up. I remember we used to work our asses off to get our first mount back in the day of classic WOW. And higher levels meant better and faster mounts. With every expansion or patch there is always new mounts and pets introduced. GW2 does not even have mounts, as if some peope are religiously against them, and instead you have all those ridiculous portals to make travel a bit more manageable. I mean how silly this is. Noone is looking forward to a new portal as he explores and levels up.
Another reward is eligibility for new dungeons. In WOW you know that as you are questing and levelling up, you will be eligible to visit new dungeons, from a very long list that WoW offers. WoW dungeons alone are in a world of its own, in terms of size, complexity and rewards. You come out dressed in blue gear making your next area quests so much more easier. And with LFG it is all automatic, sit down on the PC, enter the LFG, go questing, and in a little while you are teleported to a dungeon.
Crafting is also rewarding in WoW. You can trade for mats usually at the AH, you can level up some profession and receive some rewards for doing it, all very straight forward. WOW is not like SWG in crafting but at least it offers some rewards for taking the time and effort. And it is achievable.
You have also factions which offer their own rewards, eg pets and mounts. If you are a hunter you can also go about collecting rare and exotic pets, then go back to the main town showing off. If you are a collector you can collect rare mounts.
I have friends that have 200 pets and 150 mounts. Just for my son, once we went around collecting mounts and we got 50. We had to work for many weeks to run some instances that dropped some rare ones as well as travelling all over the place to get them.
And finally you have raids, and there is some PvP. I am not a PvPer so cannot say much about it, but I know PvP is not huge in WOW, but then again I presume with the WoW subscriptions, the PvPers in WOW are probably more than in all other games together.
In GW2 I am not sure what there is to do - what has changed or added in the time I was away.
Questing was more like drifting around the map, without even looking at my level. Did not manage to make it into any dungeons, not sure if there are any.
Area events were a lot of random people all running in some similar direction and typically attacking some lonely guy at the end who had some ridiculous HP and was completely obscured by all those players. Or fighting some spawns that appeared for no reason and everyone was attacking everything. After a few times doing that I found it random and silly.
Crafting was unrewarding and mats were very hard to gather and required a lot of management, I seem to remember something like a bank where I had to put mats in, and I had to be at the right place too, all on foot.
Can you please tell me what the game offers rather than what the game lacks in (I know people prefer to complain on forums rather than praise)?
