Question for you: I still need the Warp/Incinerate/Disrupt (whatever) trophies. Should I do a quick run on easy to get these, or do you think I can get them in the run of play on Insanity? I think I'm going to just plough through Insanity as fast as I can, doing the bare minimum number of recruitments etc., just to keep the plot moving.[/QUOTE]I picked up all of the 360 achievements for Brawler, Warp Specialist, Incineration Specialist, Overload Specialist and Tactician during my current Hardcore run as an Adept, and ended up grinding through those achievements when I found spots that would work to do them. It's best to find a location that you can pick up some of the trophy, go back, reload the save right before it, rinse, repeat.
The counters are cumulative within the game, so it doesn't matter if you go back over and over again with a repeated reloading of a save to grind to get the trophy.
