Well, the short answer is "because you have it in Dwarf form". The human form build variant, like any build variant (especially for Kheldians) has pros and cons. You gain some advantages and take on other disadvantages as a result of the way you've chosen to pursue the character's build.
One of the most obvious advantages of choosing a human-only variant is slotting. By dropping 13 powers out of your build, you've vastly simplified the task of effectively slotting your character. You can also take maximum advantage of passive powers such as Fitness and toggle powers such as Leadership or Fighting.
On the flip side, the most obvious disadvantage is the lack of mez protection (outside of Light Form). The argument has been made in the past that Scrappers and Tankers get mez protection toggles and therefore a human-form Kheldians who has shield toggles and melee attacks similar to these archetypes should likewise be granted mez protection. It's easy to see where these people are coming from, but that argument only holds if you assume that the human form Kheldian is intended to function as well as or better than a Scrapper or Tanker. As a generalist AT this just isn't the case. The Kheldian can make up for this in other ways including control powers, buffs from the inherent and a nuke - whether or not this is a worthwhile tradeoff is subjective, but it's there. The human form Kheld is therefore more like a Blapper/Scrapper hybrid than a "Scrapper form" and at least in my opinion that's as it should be. Even in single-form variants, the generalist AT should still play like a hybrid rather than trying to ape a single role that it won't (and, I believe, shouldn't) equal.
So that's the long version of why there's not mez protection. Short version: because the Devs don't want you to have it and they hate you.
P.S. As for Restore Essence, it already provides XP Debt protection. I'm not sure why it doesn't allow EndMod slotting, as most other self-rez powers allow it and the power does give you endurance on resurrect. Possibly an oversight - I can't see any reasoning for that one. One other thing the power doesn't have is a few moments of invulnerability to allow the player to get toggles up and running, another feature many other self-rez powers have. All in all, Restore Essence could probably bear a good looking at.

I understand now, thank you for your time. By the way, we agree about the importance of realizing that Kheldians are neither Scrapper or Blasters (or Blapper's for that matter), but Kheldians, a truly fascinating combination of all the other hero AT's.

Greetings,
I am playin with a PB atm, which I am enjoying a lot thank you. I though have a question about the balancing of the secondary powerset, Luminous Aura. While I don't understand much about powerset balancing, but I have an idea about these measurements are going to make the set more "it". Thus, my question(s): Why doesn't Restore Essence include endurance modification and debt protection? And why is it that the "human form" Peacebringer, Light Form not included, isn't given any status protection what-so-ever?
I thank you for your hopefully useful replies ^^
