I recently got my Mesmer to 80 and am beginning to look at putting together Exotic gear and finalise my build. Currently, I play PvE, but am considering giving WvWvW a try in the foreseeable future. The prospective build is:

I shall explain my choices here.
Firstly, I have grown quite comfortable with Greatsword/Sword+Pistol. I recognise that Staff would probably be more optimal than Greatsword, but I prefer this weapon. Phase Retreat and the Staff Clones are excellent, but I prefer the functionality of Mirror Blade. Similarly, I much prefer Phantasmal Berserker to Phantasmal Warlock. I find Mind Stab near useless, but I find it a small price to pay. I mostly use the Greatsword for those two skills anyway, using the Sword/Pistol as my primary weapons for engaging in combat.
My combat style is largely Shatter-based. 90% of the time, I throw a coupe of Clones and a Phantasm, let the Phantasm use its attack (it seems a waste, otherwise) then Shatter. For 1v1 against weaker mobs, I Mind Wrack. Many vs Many situations, I find Cry of Frustration useful. I rarely use Diversion, mainly using it as an Interrupt when Magic Bullet is on cooldown. I regularly use Distortion against more powerful enemies (eg Champions) or when dealing with a group of enemies at once (use Distortion, Sword auto-attack to stack some Vulnerability, then Blurred Frenzy for more invulnerability and damage; 2-3 Illusion Mind Wrack to finish the job).
Ether Feast is the best general-purpose Heal we have, so no need to justify it :P
In Utilities, I have Null Field for condition cleanse. Honestly, I sometimes with this thing had a 15 second cooldown :P Decoy is mainly used for its Stun Break properties, though I sometimes use it defensively for the Stealth (eg if I need to make a little distance and am out of endurance). I am currently experimenting with Signet of Midnight as a second Stun Break and defensive tool. In my third slot I have previously experimented with Blink (I personally had a lot of difficulty using this well; probably not a skillful enough player) and Feedback (which I rarely used; more on why later).
I have honestly never once found any of the three Elites useful. I think Time Warp would be the most useful if I get into WvWvW or learn to play Dungeons.
Traits. I originally used Kai’s levelling build, and have been experimenting with it since.
Domination:
- (I) Mental Torment to make better use of Mind Wrack.
- (IV) Rending Shatter, as I suspect the AoE Vulnerability will act as a force multiplier, thereby making my contribution in group situations all the more valuable. Still experimenting, however.
Dueling:
- (II) Phantasmal Fury just seems plain useful. Phantasmal Berserker and Phantasmal Duelist both hit multiple times, so with a bit of Precision and Fury, they have a good probability of multiple crits for more damage and more Sharper Images Bleeds. YUM!
- (X) Deceptive Evasion seems essential for any Shatter build to get more clones up faster. It is also awfully useful defensively, as it often takes aggro.
Illusions:
- (IV) Masterful Reflection is the reason I rarely used Feedback. Though the duration and cooldown are not as kind, the fact that it covers all enemies (rather than a small group) makes it potentially more useful (IMO).
- (VII) Illusionary Elasticity is another I am currently experimenting with. Since Mirror Blade and Magic Bullet are both skills I make extensive use of, enhancing them seemed worth trying out. Currently undecided.
- (XI) Illusionary Persona. A no-brainer skill for a Shatter Build and it makes an absurd enhancement to the value of all Shatters.
