I dont think there is meant to be completion rewards as you get rewards for each section including the final boss and from the chests. As for what you get, besides the shader you will get the same loot the rest of the raid gives you.

Then there is false advertisement in this raid. If you have ever done a daily, weekly, nightfall they all have a section called rewards which is what you will get once the "Objective" is finished thus, making the rewards section of the mission vanish after you complete the objection and proceed to the reward screen. So if you do a daily level 24 the rewards will be 1x ascendant materials and you will receive the material in the missions summary reward screen but at the end of this raid you are stuck in the raid because the bug causes you to hit the 0 count down in mission complete but stay there forcing you to go to orbit, I've ran this raid twice making sure that this wasn't a one time bug. Read my fourm post for more info on this bug and what happens if you'd like.

I know what you mean i have had it happen to me and i think it happens to everyone ( i personly know atleast 8 people in different raid groups who have had this happen and i dont know a single person who has seen an end mission screen) which is why i think there is no end of mission screen. Even if there was an end of mission screen i highly doubt it would give you more items than you already got through the raid. Also perhaps what i said before was not that clear, what i meant was i dont think there are any specific rewards for getting to the end of the raid, i think the rewards the mission description is talking about are just rewards for completing sections/bosses and the chests.

Check out that link i have above, my clan mate Mer has a very compelling reason why it is a bug and not just the end of the raid.

I did read that but i have quit out of daily heroic story while the timer was up and still gotten the rewards and the reward was still removed from the mission description. which is why i am unsure about that argument.

I got your answer for that if you go to orbit while your countdown begins you will receive your loot in orbit to the right of your screen, yet we received nothing while returning to orbit for the raid. Destiny wouldn't change its algorithm that its used for every single thing for the rest of the game just for a raid that was created with the rest of the game that's just plain stupid you know?

I know what you mean but they would have to have made some changes to how that code works for the raid to drop loot like it does from completing individual sections, I imagen it is the same as the code for strikes and missions just modifide to give you the loot befor it would normaly send you back to orbit and then remove the part that sends you to orbit and replace it with a trigger for the next part of mission so they did not have to writh new code just for the raids. Also becasue you are getting loot befor going to orbit they must have dicided they did not need end game loot screen. Ether way i dont think you would get much more from an end screen than what you got from progressing through the raid. edit* This is coming from my experience programing and i usually try to come up with a bit of code that can be used for many different parts of the program with little to no modification and it looks like that is what they have done here.

They don't and wont have to remove something to add something like phase loot in, its just RnG. ;P and if you get nothing from basic RnG you are guaranteed 100% shard or energy drop.
