LEGENDARY Difficulty

As we all can see, every few updates we get higher difficulty with new challenges and rewards. I personally love this direction and hope it will be further explored in the future.  

With time passing, more and more players are completing every operation on every difficulty, as it becomes easier with practice and focus we can gain on every attempt, either successful or not. I hate to say that, but eventually game will become boring - I know it was said many times before but it is truth.  To prevent, easiest solution is of course adding new difficulty level with more rewards, new Ordeals for Data Vault and craziest stuff you could imagine to overcome during Operation. We are getting closer to it with every released difficulty but we are still far from point we should be in. If I can finish it on 2-3 attempts, or often on 1st one, then it wasn't hard enough.

I can see every time new difficulty is implemented, Developers are not sure if that's not too much; to my horror there were even cases when they came to conclusion it was too much and nerfed what was added. 

I would like to see difficulty designed without such concernes. Makes us feel like survivors from Instvaan, make us feel like Loken when he 1 vs 1 Abaddon, make us feel like Garro fighting deamon solo. Give us a chance to become Emperors Finest!

I have few ideas about this new difficulty. 

1. Basic reward - resources. People who would play it probably don't need resources at all, but still it is annoying to have 3 green, 7 purple and always 20 golden ones. So make completion of such Operaion reward us with 1 green, 1 purple, 1 golden. 

2. Completion reward - in my dream, considering the difficulty, we should get one cosmetic item for completing each Operation lets say 5 times. We have 8 Operations now, so completing this challenge would provide us not only with full set armor but also some weapon skins (for god sake, do not make it auto bolt rifle or bolt rifle one, we have enough already. Make skin for plasma or less used bolt weapons, or bolt pistol and chainsword maybe. Last time we got skin for knife - very good idea). 

3. New Ordeals - forcing people to play PvP to unlock everything is not best solution, especially when some Ordeals placed there are just crazy. Game is focused on PvE, so it should be possible to unlock everything by playing PvE, or PvE + SOME PvP. New difficulty allows you to put in game new Ordeals. Ordeals unlocks are based on enemies but you can make new tab with LORE. In LORE tab you can describe Primarchs of Chapters we see described in Heraldry section. 

4. Spawns and enemies damage - both increased.

On top of that, there should be 2 bosses spawning on this difficulty in every operation except the ones that end with Boss fight - Reliquary, Decapitation, Termination.... Obelisk. 

Chaos has only one boss for far, so we need another one.

Idea: Chaos Champion - either bigger marine in terminator armor with some more challenging move set or something completly new. You can make agile, fast boss with less hp - some Champion Chaos Vanguard of World Eaters, why not. Or Assault one. 

5. Introduce new Ordeal giving MUCH more data points - finish mission with Geneseed. I do not understand why it is not here yet. For completing missions on new difficulty with Geneseed you can unlock Saviour armor part. What it would be I leave to you guys. I would prefere chest armor but with cape for other classes than Sniper.
