The "achievement farming" in ToT is ridiculous. Having to drop everything and get X amount of fatalities, brutalities, fatal blows, krushing blows, etc. is extremely redundant. It also seems to either reset itself or go off where I'm at with the character's towers last... which doesn't make sense? The blood spilt is okay in my book because you can just play the game and have fun with getting there. (10,000 or however much) You're still technically farming to spill more blood but at least you have a little more control to complete it.
It would have made more sense if they're going to require farming, do less per category and maybe a few at a time. That would actually reward you for being a better rounded player if you can get multiple things done during your matches to get there. (example: 5 fatalities, 10 krushing blows, and 5,000 blood spilt required) If I'm just not far enough into character towers to have encountered this yet then I apologize. I'm on number 4 with EB.
