The ring of valor was re-introduced this patch into the arena system and noticed a nice little trick. This may seem obvious to some but to others its a very helpful hint to get a large advantage to this arena.
As you can see the areas you start are the two fenced in holes. When the game starts the floors of that hole raise to the top then the fight begins. If you wait about 3 seconds before the platform below reaches the arena floor your healer can start putting HoT's on your group. I run with a DK/Resto Druid and having a full set oh HoT's prior to the game even starting is incredibly helpful.
