I hear ya Bro , I too played many of mmo's tha required alot of grinding dark age of camelot was probably the most grinding game i ever played back in it's hey day 7 years ago , And now a days thats why i'm starting to get out of mmo's because of the nonstop grinding .
for the most grinding i have done in mmo's here's a list ranked from 1 to 5
1. Dark age of camelot
2. Star wars galaxies
3. world of warcraft
4 . city of heroes
5.lord of the rings online
Although alot of the next gen mmo's that are coming out i hope do well grinding is usually the biggest concern i have going into any mmo . And glad to see a fellow player who enjoys guild wars
Just go to off topic for a second guild wars is probably the only online game i have enjoyed more then any other game and played it on and off for the last 2 years and just started playing it again

and am enjoying it for alot of reasons .
1 it's different you can only have 8 skills and for skills and builds it's by far the most advanced game i have ever seen in hack slash rpg
2. There's alot of content and you can buy all sorts of skills and elite skills to cap and go after all these titles in hard mode which is really challenging in each campaign
3. and the most i enjoy about guild wars is the instanced adventure and quest areas , no worry about camping and also this is a game that you really have to think out of th box in some way
All in all the greatest thing i like about guild wars is that it's unique there isn't really a game remotely as close to guild wars and i think that's what alot of mmo's are lacking .
Their not willing to come up with a unique vision for their game and stick to it simply because they feel that they need make major profit and therefore cater to alot of playstyles .
Don't get me wrong i don't have issues with mmo's to trying to flock to more then one crowd but when you have to takes away things that truly make your game original and unique thats where alot of mmo's go down the tube and nothing stands out anymore imo or hasnt since world of warcraft first came with guild wars imo being the only exception .
Anyways i'm a big fan in some of the mmo's that will be out later in the next few years . star wars the old republic , star trek online , dc universe online and a few others that were just mentioned recently.
But i will probably stop playing mmo's altogether in the next few months simply cause i really disliked the grind and constant camping and often enough the high level caps and such .
Guild wars 2 is most likely the only game see myself playing very actively simply because i love arena.net and what they have done with gw and that it doesnt require a monthly subscription hehe
