I wouldn't worry much about Brayflox, this is far from the hardest dungeon in the level range. I've run it as a first time War and first time Pld in the last month and neither run saw any deaths or overly-complicated mechanics/sections.

On occasion your health may dip low and test your healer and your defensive cd management, but the mechanics aren't tough and the pulls aren't overly scary. Learn what mobs do what and prioritize those with abilities.
