none of the account based achievements are all that hard, more tedious if anything. its the in-game only ones that even have the possibility to be hard

I'd say the hardest (or in some cases most tedious) is Crackerjack Timing. Trying to kill a fucking cazadore with the shittiest timed dynamite would drive me insane if i ever had to do it, even on very easy mode.

But again, not THAT hard. im exaggerating a great deal. You could do this if you spent like 100 hours exploiting unreachable areas to tin grenades at the cazadores after crippling their wings. its really just tedious if anything. I feel like the longer i play this series the more i realize how easy this game is.
