W/N or W/E

I plan on making an axe spiker, and I was wondering what secondary to use,
Necromancer for Plague Touch
or
Elementalist for Gale?

I think either would work, but I do not have a lot of PvP experience, so which one would be more effective?

4 on 4 - plague touch
8 on 8 - gale/shock
plain and simple

I understand the logic behind that, but it does not really help me much. I only recently got guild wars, so I need to play through the game to unlock the skills. Also, as of right now I play mostly GvG. I want to know which set I should use to play through the game and acquire these skills and knowledge of how to effectively use them. I know that PvE and PvP builds are usually quite different, but I need to unlock the skills in the first place.

My first char was a W/N...I've never looked back. He can farm, and pvp quite well (play with TSH).

hmm im a W/N and do enjoy it but you do look at the other professions and wonder...
