Guild Wars 2

I’m seeking for answers, please help :O

1. What is the best weapon set for leveling up a necromancer?
2. What is the best trait combination for leveling up a necromancer?
3. What are the types available in a necromancer (Like a support type or puts tons of conditions etc.)
4. What is the best end game weapon set for necromancer?

To 1. . You can easy level a neco with all kind of weapons sets, just look for something that goes well together such as : dagger/warhorn axe/focus | staffscepter/dagger just to name two options. There are alot more options that are just the two i leveled my necros with.

To 2.: You should alway adjust your traits to your playstyle. If you decide to go for a condition orientated leveling buid then search for traids that benefit that playstyle. same goes for power build.

Power example: http://gw2skills.net/editor/?fQAQRBHbhG2IjW6elmyG9eCRqQzA9YXqFnh6h7sOfIA

i used those without any problems.
Another option would be a borring minion master build which i will not list -.-

To3.: Necros can do everything they want, like any other class. It#s up to you to decide if u wanna do burst dps/ heal support/ play minion master / play with alot of wells or play with conditions or a mix of any of those options

To4. there is no best end game weapon set only best at for example power burst or conditions
