Something i don't understand about Death March is the fuss some people make when playing on that difficulty. I remember reading up on a few Death March tips before starting as it was my very first game on TW3. I read people saying "you don't get away with XX or YYY on Death March", need to read the bestiary, apply oils etc etc etc. Come level 15ish, tactics don't matter a jot. You can still get away with umpteen mistakes, Quen is all conquering still and come the end, it really is no harder than playing on whatever the lowest difficulty is when you first begin. Other than 2 out of the four Wild Hunt boss fights, I never struggled. In fact, I expected the last boss fight to be traumatic as I initially struggled to beat the first proper wild hunt boss on top of the mountain and the 2nd to last boss was a pain until i realised his attack pattern was all but 3 things.
Quite bad when you consider a pack of wolves are your main threat and they soon become irrelevant too. I'm no uber gamer, in fact, I'm usually pish at games, but this was a breeze. Not saying I didn't die, but I would say 3/4 of my deaths were my own doing. Like "ooooh, this boss only needs one or two more hits, no need to quen, chug a potion or roll away", then I'd get smacked into the ground. I think I had around 8 deaths that were down to being properly owned by what i was fighting. 6 of those happened during facing the wild hunt, not the end boss either as I did him first time.
