mes/e or mes/n

i want to make a mesmer but im not sure about the secondary. im not really interested in being able to handle both melee/cast so i guess im favoring mes/e more than mes/n but id still rather get an opinion on it. also i was wondering if it was practical to include a ward or two in the skill build if i decided to go mes/e if not a list of the most effective skills to do the job of a mes in pvp would be helpful.

Mes is pretty much a full-time job in PvP, so you're gonna have at most 1 or 2 slots for your secondary class.

There are a lot of necro curses that complement your mesmer skills, stuff like chillbains, lingering curse, spiteful spirit, rend enchantments, and a bunch of others that I'm forgetting, all of which go very well with your caster-shutdown mes skills.
On the other hand, there isn't really much you can do with a couple of free skill slots and elementalist skills. There are some tricks and whatnot that you can do as a Me/E, but in general, I'd prefer Me/N.

my first character was a me/e. At first i loved it because i got all sorts of cool hexes that would immobilize the enemy, then i could wail on them with fireballs or firestorm. But eventually i got more and more usefull hexes, and alot fewer usefull ele skills. Maybe i just didnt get the right ones, but eventually i was only using aura of restoration and a bunch of hexes.

i've also played a necro, and now from my experience, i would go me/n. With all the curses and hexes, you can either stack so much crap on an emeny that they'll be mincemeat for the tank of your party, or you can immobilize them with your mes hexes, then use death magic necro spells to kill them.

well i guess my best bet would be a me/n after your suggestions, but could someone plz give me a list of the best 8 skills to use that will most efficiently complete the job of a mesmer in pvp and gvg?

also.. are mes/necs the best build for a pvp mes or is there a better secondary, im open to suggestions, im really clueless as far as mesmers go

The mesmer has many roles.... e.g.
melee shutdown
caster shutdown
energy denial
interrupter
support (hex removal etc)

a good interrupter would be:

Fast casting
Domination
Illusion

Arcane Conundrum
Migraine [E]
Power Leak
Power Spike
Power Drain
Diversion
Shatter Enchantment
Res Sig
