Well, looks like a solid concept , I run a similar one myself and it tears through HM. I like how the AoD/Orders covers a dual role in the party, but that itself won't be enough to sustain in HM. I suggest that on yourself you bring Ebon Battle Standard of Honor, The damage from the para's+orders still won't pack that much of a punch and its always nice to have extra damage from the party, in general, from the ward. I'd also suggest maybe finding a way to put Splinter Weapon into your party as well. There's a lack of AoE which is a key concept when going into PvE, but is not always the case (Discord); it also adds that much more damage to your paragons.
The paragons themselves are a seperate issue which I'll start with your first. I see that you have Defensive Anthem, its a great skill, but there are better ones that might suit your team better; since half of them are physicals. That paragon looks like its dedicated to the command line, so I'm not going to suggest to swap with a defense-supportive skill, since Command is rather oriented towards being offense-supportive, again with a few exceptions. I think it would be a good idea to maybe look into Crippling Anthem, I know that cripple isn't a large factor in PvE, but you have to keep in mind the slow AI of the pets and travel-time, So cripple may serve as a useful function to keep your enemies closer together, and slowing down physicals trying to get to your back line. Bladeturn refrain isn't that good of a skill in general, so maybe swap that with Anthem of Weariness/Flame to for more synergy with the other paras, or another utility skill (Fallback, maybe?)
I'd leave the second one As-is, but maybe throw in Blazing Finale; Heroes actually use it rather well on pets in my expierence. The third Para needs a bit of work though. First, it needs at least one attack skill, you want to exploit the fact that paras work well together so if you have one attack skill you can benefit from all the shouts that trigger on them. Second, I'd ditch Anthem of Restoration for Purification; Not only can it git rid of party-wide conditions quickly, but it can be a life saver for when your physicals are blind. "Find their Weakness!" seems a bit irrelevant to the build, so that would probably be the skill I swap; maybe try Vicious Attack since you have two copies of "GtfE!".
All-in-all its a solid concept for a team build, but I'd make a few more adjustments, that would overall boost your healing/damage output as they lack with your current setup. Your Curses Necro can go /Rt and bring Splinter+ARage. Also, you can probably make your E/Mo Protter go hybrid, since you can invest relatively a small amount of points into Protection Prayers and it will still be effective. The Ineptitude Mesmer seems like an excellent source of damage and is an all-around effective build, but it seems to be out-of-place with your team and lacks synergy with them. I'd suggest that you maybe consider a different hero that can add more to your team, instead of just raw damage.
I hope you found this post helpful and that your future endeavors may lie at peak prefromance.
Oh, next time add attribute points too, please.
Edit: Ahh, remember as well that Pets are treated as "Allies" not Party Members, so make sure that you read the descriptions to see if they affect your pets. Also, Black Bears would be particularly useful for your teams since they have the inherent skill "Brutal mauling" which can trigger a few of the Paragon shouts.
