Guild Wars 2

hi im new lvl 80 thief an am struggling to realise how thiefs stay in stealth so long an still maintain massive dmg was wondering if any1 could explain, so far if i go dmg my stealth is low an if i go stealth my dmg is non existant even in zerker gear

was wondering if some1 could link a good wvw d/d build and a staff build for dungeons/fractals plz

they also were both just in the desolation garrisson an didnt fight each other
