McDon: Level 11 Mesmer.
I like all variety in MMO, in other words, no aspect is my favourite, however I'll try explain my problem to help you decide further.
I quit before because the I got sick of the questing. It seemed repetitive to fight hordes of enemies with the same moves to get to another area. I like WoW so it's not the MMO gameplay, but I can't get the subscription atm. Just looking for some interesting alternatives or at least a way to make the questing more "fun" or "interesting".
Hmm. Do you have the other chapters available, or are you limited to the first one?
Generally, Guild Wars allows tons of different builds for each character class. You can switch secondary classes freely, and you can respec your character completely at any time for no cost - the only thing that you can't change is your main class.
However, the first part (Prophecies) is different from the others in that character progression is very slow, you are limited in the skills you get at the beginning (and therefore limited in the builds you can make), and you need to complete about 2/3 of the game before it allows you to switch secondary classes. The later installments (Factions, Nightfall, Eye of the North) all make this possible much earlier. You can switch chapters with the same character anytime, so if you have it available, I'd suggest to check out Factions, which gives you the most flexibility in skilling your character.
If you are limited to "Prophecies", then I'd suggest taking taxis to Lion's Arch and Droknar's Forge. Unlocking these two locations gives you much more flexibility in where to go, what to do, and how to skill your character. (You can also buy better armor there, though that might make the earlier areas too easy if you want to return to them.)
Also, if you like collecting / achievements, you can try to work on the many "title tracks" that the game offers.
