I think one of the hardest things about doing very hard stuff is failing when you are soooooo close to success.
You work so hard as a party to bring down the boss, deal with so much crap. Get it down to ONE percent, then....the party wipes. UGH!
It is sooooooo disheartening, coming so close only to choke in the end, and even MORE so when it happens multiple times in a row!
Case in point; I decided to join a group that was doing the 2nd instance of Coil synced and minimum Ilevel. for the challenge. I thought, "hey, it wold be pretty cool if I cold say I did this!"
So we tried, and tried, and tried some more, each time getting better at it. That stupid last sphere kicked our butts over and over, but we got used to it and starting knowing what to do. But we just could NOT do it. Soooo many times we got it from 5-1% and failed because something happened to kill everyone.
I don't know if they ever did kill it because I had to leave to go to work.
Yeah, it takes a truly dedicated group NOT to be dismayed by THAT. over and over. ;-)
