after lvl 20

do u still get attribute and skill points? how can u advance ur character after lvl 20

You can still earn skill points, and up to 30 more attribute points, but all other character advancement is in the realm of new skills and equipment.

Every time you would "level" you gain a skill point. There is a total of 200 Attribut points. And alot of game left for you to play...

I've been getting more skill points - but how do you get more attribute points once you stop levelin?

There is a mission in agury rock to meet up with a forgotten lizzard, from there you get another 15.

however i do not know where the other fricking attribute points are.. tips?

One quest is the gorge, northeast to augury rock, there is a forgotten quest. Do that and the npc will give you another forgotten quest for 15 pts.

Then you have to finish one of the four 2nd profession conversion quest. Upon completition, go Draknor's forge to see Yanyi or Vanyi, there is a quest called hero's journey requiring you to go hero's audience, gorge and ... seeker's refuge. When you finish that, he will give you another one called hero's challenge. You have to go west from Iron mines to coppermine.

It is a hard trip, there are many ice based mobs slowing you down, so you can't run for it. That is why the quest reward is 5,000 xp and 15 attribute points.

can you convert back to your original secondary profession and still do the quest.. or must you stay with the secondary you converted to until the end?

you can do both

I rolled the lvl 20 3 xs and have NOT received any skill points. I tried writing the support team from Guild wars and haven't heard from them. This is a real bummer....
