Worried about this combo for arena.

[tripleboxed]

Well as you all know arena is though and takes skill & a lil luck especially with us multiboxers why im worried? well im having fun leveling my team im just not sure how well they will preform at 80 with little dmg brust & my goal is to obtain wrathful s8 on this team i will mostly be pvping with guild mates i currently am leveling a disc priest + 4 aff locks which is smooth for dps. i enjoy hellfiring/holy noving a bunch of mobs at level 70 i can see its going be rough to get a decent rating with arena having so many geared players, the thing is these opponents of mine most likely cant not play their class correctly still leaving they to a victory for the very fact of my gearscore & team combo. i would like to know any one out there currently or have done this combo type and had positive experiences?
