Help me understand t10 a bit

28% is insanely huge :S even if every dps was playing their class in a somewhat lazy way that's still almost unheard of. And yet your add phase stacks sound perfectly normal, so your DPS can't be playing their jobs in such a bad manner as to be 28% behind schedule. There's a lot of breathing time for BLMs to cast between mechanics which come every 30s or so, it just doesn't make any sense unless people are dying left right and centre in the last phase. Don't suppose there are videos of these runs?
