"...plain old memorization to get out of a scrape." Noooooooooooooo! Have you not played Rainbow Six: Vegas Terrorist hunt? The variation of tangos locations in that game is excellent and is what makes it so enjoyable to play game after game. One of the things I though had magnum cheapness was they way you had to memorize sniper placements when playing on Legendary just to get past them. Into the Belly of the Beast is one of my favorite parts of playing Halo on Legendary because of the variation of enemies you get from one attempt to the next. Please keep this variation in H3 and render memorization of enemy placement useless. Especially on legendary. Also, please do not make it Legendary difficulty by nerfing MasterChief while leaving everything else as it is in normal. Instead leave MasterChief as he is in normal and crank up the enemies precision, aggresiveness and above all, their quantity. MasterCheif should have to face huge hordes of enemies, not be made easier to kill then some technician.
