PvP/Priest + 4 Arcane Mage Combo Thoughts?

[tripleboxed]

im starting a new pvp group this week and wanna know your thoughts on this team i thought would be most fun for me anyways priest + 4 arcane mages im not sure what to spec the priest. i do know the priest will be not be casting much. as my mages will be doing most of the casting and mana burning. arcane burns mana fast so ill have my mages use evocation and my priest use hym of hope at the same time to gain most mana, i was wondering if that was a good idea as well also holy nova and arcane explosion this would be good as it heals the mages and hits surrounding enemies.

i was wondering what kinda consequences would my mages have and my priest would have anyone who can share thanks

oh and i use isboxer
