Shouldn't you receive higher Mk rewards when repeating missions? Shouldn't you receive the item it shows that you'll receive? I'm level 40 and doing missions that say they'll award Mk X items, but I get only Mk IV. Did something change because it didn't used to be this way.

Stop trying to break the game
At least many of the mission rewards will upgrade for free all the way to Mark XII when put in the upgrade window as you discovered.
This is the only change I can think of aside from being able to skip through missions and take them out of order if you've previously played though them on a different character who's reached level 65 as you are doing.
Your Chroniton torpedo drop shown in chat is level appropriate so things are working fine.
