The burn such an easy dungeon once know the final boss mechanics everything before the final boss was incredibly easy to burn through & final boss loses it's difficulty after one attempt, have run into no more issues after seeing it once.
I really don't like the comparison though since when people talk of the Burn they usually only referring to final boss because if you think rest of that dungeon was a challenge then damn you've had a lot of bad groups I barely remember first two bosses because how quick they get deeps down.
