The "General Executioner" achievement, i am only missing one of the generals but have been farming for many hours now...
any time something that is purely based on a % chance, and therefore luck i always get the short end of the stick... so i have come to violently hate these kind of things.
its always been like this... this one thing that took people i know less than a few hours, took me a week once... farming the same mob with a 15% drop chance on the item i wanted.... for a week straight...
on the oppsite side of the spectrum, things like the "Dodge 100 lightning bolts" challenge in FF10, i managed on the first try.... if no luck is involved i can always get it done.
these things always feel like the most cheap way to introduce "challenge" into any game..
I play every class in every situation. I love them all.
