Guild Wars 2

Haha that’s what confuses me about this game!
Everybody’s got different opinions on builds / weapons. I’m guessing there are more viable combinations I can use so in the end I will just have to wait and see.

Hi i got a few silly questions.
I did look around but i got really confused so i decided to ask here instead.

So I’m a new GW2 player. (First char)
I’m playing a mesmer and I got to lvl 37. I was using just random weapons until level ~25. Level 25-30ish i used staff/sword+focus and 30-37 i used a combination of staff&sword/sword+sword&focus.

I really like staff but it feels like I’m killing too slow and I like focus cause of the #4 skill speed. Now with all the leveling “builds” there are i got a bit confused. I’m struggling with leveling and I heard it gets easier at ~60. Now which build will get me to 60 without thinking of killing myself too much?
I know some ppl recommend phantasm build while others go for clone cripple(?).

I feel like I’m doing something wrong cause I kill mobs too slowly and sometimes I feel like I’m dying more than I should. (Though it only happens with dynamic event bosses…not so much with normal mobs)

Help pls
