Guild Wars 2

I would like to hear opinions (and experiences) about running a tournament build without condition removal. I am especially talking about shatter builds like this (20/20/0/0/30 build):

When I play other classes, condition removal is always an important part of my build. As mesmer, I usually take Null Field. However, I see a lot of builds without any condition removal. How do you guys fight necros, condition rangers etc. without it?

kill the necro before he kills you , be sure to daze his ds#4 or his heal.

null field suck, isnt effective reomving condition so people dont use it and prefer MI ( or decoy for defensive or the illsuion life to revive players) to burst down quick conditions builds. null field will do nothing for you againt a Necro/engi condition, only good against thief/warrior bleed but how many of them exist on tournaments?

if null field work as description than will be a amazing utility, right now for me is useless.

i used null field on begining when i start play mesmer, because every class need to have somthing to remove conditions right? forget it, better to have something else to burst down more quick the condition class builds
