Guild Wars 2

I recently started playing my necro (lvl 38 now using staff. and scepter and dagger off hand) again after playing as a Norn warrior (lvl 31) Sylvari Ranger (lvl 74). At first I continued playing my necro as a minion master but I soon found out that the minion AI is just derping, and the minions die within seconds And I still get all the aggro instead of my minions. (I am NOT playing WvWvW or PvP by the way)

So I though ok no problem I just change my build and things will work out better. so I replaced my slot skills with wells. And I am putting my trait points into spite,curses and death magic. And I still feel kind of weak…..With my ranger I could at least keep enemies at bay. But with my necro I just cannot seem to do that. Sure the wells do quite alot damage but the cooldowns are quite long. I even have trouble in areas where I am down lvl’ed.

So what am I doing wrong? Or is just me or does the necro feel kittened? Could someone give me some tips and tricks?
