Elites should really be something special that has a great affect upon how a character works. Many of them do this but there are quite a few that just do not seem to be on the same level. Maybe I am way off on some of these and there are builds that can take advantage of them but here is a list of elites I can not think of a use for, at least in PvP.
Monk:
Healing Hands(Even in NR stopped I would still rarely run this)
Shield of Deflection(Aegis and/or wards are just better)
Honorable Mentions:
Unyielding Aura(has its uses in 4v4 arena)
Word of Healing(many love it but I hate it...with 3 monks in most groups you almost never see the bonus)
Elementalist:
Glyph of Renewal(the poor man's oath shot)
Mind Burn
Mind Shock
Mind Freese(The mind spells do not do enough damage and thier effects are not up to par and they cause exhaustion.)
Honorable Mentions:
Thunderclap(It has a great affect if you do not mind wasting your entire energy bar to interupt someone for a couple seconds.)
Mesmer:
Keystone signet(when you can already run mantra of signets or inscriptions there is little to no use for this skill)
Necromancer:
Aura of the Lich(this is a liability as all the degen that is common in PvP will kill you even faster)
Ranger:
Escape(besides trying to run to outposts I see no need to waste your elite spot with this skill)
Practiced Stance
Melandru's Resilience
Punishing Shot(why not just use distracting shot)
Ferocious Strike(ha!)
Honorable Mention:
Crippling Shot(has it uses in some cases)
Warrior:
Cleave(Does almost exactly the same amount of damage per adrenaline as Eviscerate but does not cause a deep wound)
Defy Pain(Another skill only useful for running to outposts)
Flourish(most attacks recharge so fast I can not see this being useful)
Warriors Endurance
Ok if you know good way to utlitze these skills come forth! Or suggestions on how to improve them. I have every elite in the game unlocked and would love to incorporate all of them into a build at some point or another.

When operating in areas with many condition and hex users (bog scales, summit arcanists and so on) you are nearly certain to have 3+ on you, which is 3 pips of energy and 6 pips of regeneration... work for me. In PvP it may not be a great choice, but the Melandru's monk does have it's uses. Ferocious Strike as has been mentioned is brilliant - if your pet is alive.
