One question I like to ask to the OP. Was your ENTIRE party there present from begging to end as you mention you were there. If the answer is um 'no'. Then no matter if you are whm/tank spamming medica/flash, DPS pulling max damage, you are NOT going to get full credit on those fights.

If your party was there, all 8 members present at the target, than I suspect that someone was doing nothing.
