Brayflox is pretty fun when you don't have s--- for brains PUGs to deal with.
First time I did Brayflox with my tanking PLD companion, we got DF'd with a BLM who basically said "f---ing Flash after every combo" so he could AoE burn mobs down. Mind you, he was in gear from Toto Rek and lower and by the time we killed the first mob, the second and third mob only lost about 5% HP and I was basically hitting my Cure button over and over again. He was cussing and screaming at my PLD so she said goodbye and dropped and I said good bye and dropped with 'em. Have fun queueing up as DD again.
But yeah, Brayflox is when the kiddy gloves begin to come off and interesting mechanics start to filter into the boss combat. It's not hard persay, as I generally do Brayflox with a WHM WHM PLD BRD setup now a days for giggles (yes, my group of friends have too many WHMs leveled), but it's when the difficulty begins to increase in the game.
