For clarity, by 'randomise' I mean if there are say 10 objectives [1 per wave] then when you play game 2, 3, etc you won't get the same order each time OR there are a pool of say 15/20+ objectives which can occur and each game you get a random selection from that number.
I wouldn't mind if the final one [4th, 7th, 10th] was the same each time [as in for that map as opposed to simply being the last task before Boss/completion] but I'd like to think that if I load up say Nuked I won't be doing the same stuff, in the same order, ad infinitum.
Make sense?
