Need help choosing endgame build
Depends on if you have a set group of friends (and if so what professions/builds they are going), but if not; going wells with all out zerker is nice for pugging and speed runs
I run in an organized guild zerg[not mine] in WvW. I use marks/wells and swapping signet of the locust/spectral walk with plague form.
Staff 3 followed by Staff 4 is your own combo creating area weakness.
On offense spectral walk then plague form is a mobile shutdown as everyone is spamming 1. Wells can finish the downed so you can keep moving.
On defense/choke points use the marks for weakness, followed by wells to create vunerability and convert boons to conditions then plague form to seal their fate.
Staff and wells also work on walls. Wells with projectiles gives lifesteal combo which works on camp supervisors with RI.
Also get yourself more inventory space, you’ll need it.
The beauty of Necromancer is that there is no one perfect end game build. Start with a staff and scepter/dagger putting 20+ points in spite, curses and toughness. Use the cheap but awesome runes of the undead. That will give you a lot of skill variety from which you can build experience and your own style.
