Guild Wars 2

can you guys give me just some tips about the classes and the primary stats they need to have… in order of importance for example:

warrior: toughness first, vitality , precision

ranger: precision first, vitality,….

elementalist: vitality first, power, …

those examples was just random i dont have knowledge about the game so if you guys can give me some tips about this =)

i played this game for a week and never got any error before.

today i was playing for about 20 mins and this error 58:11:5:218:101 kicks me out.

i tried again and played for about 10-15 minutes and the same error kicks me out.

58:11:5:218:101

this had never happened before, what could be?

crowded servers, problem with gw2 servers, normal error somedays or what?

i’m kinda lost here, would appreciate some help to solve this question.
