I don't know if there's a better place to do this, but a group of mentors took us through Leviathan Extreme, min ilvl and no echo. Two of us, including me were first time clearers.

The party stuck with us even with numerous wipes, really bad mistake(s) on my part, etc. but I did learn a lot and trained me to better read the field.

I won't put names on here for privacy's sake, but thank you to all who stuck with us and for the numerous tips, callouts and recoveries. It was certainly an experience that I hope to pay forward sometime when I get better at the game... hopefully...
