Brayflox was the first dungeon in which I actually died, and I was well geared and level 33 (WAR). From conversation and observation it seems as though this is one of the first jumps in dungeon difficulty, when CC and smart play actually start to matter. After we figured out that everything was hitting harder and we had to be on our toes, I used my cooldowns more often and the healer wouldn't let me drop as low. Bickety bam, the whole stage comes down. Point being, I wouldn't be worried yet.
