i am setting up the same thing...


basicly looking at spells i decided to go w/ the Spriest as my main

reasoning: some spells can be cast while moving others cant ....also all my cooldowns (ie mind blast) and cast times are longer on the shadow priest (ie flay is 3 sec ...no warlock spell is 3 sec w/ bane)
So the lock might sit idle for .5 sec after he does his bolt but that is better than the alternitive of burning extra mana on the priest starting a new flay early. also the 6 sec cool down 1.5 sec cast on mind blast doesnt match any lock spell nicely but basicly what i have come up w/ is :

priest

1) MB
2) pain
3) flay
4) VE
5) VT
6) death
7)aoe fear

lock
1) UA
2) corrup
3) bolt or curse of shadows...havent decided yet
4) siph
5) immol
6) shadow burn ......i am a little concerned about this as the priest needs the killing blow to not get backlash...we wil see how this works
8) aoe fear

w/ the standard mob they should be dead by sequence 1-2-3-6 or a 1-5-2-3/6 in reality

we will see i still need to test this. guesss it depends on your locks spec too ...my lock is afflic 41/20 destruc w/ 998 shadow damage ...in mostly epics i dont want him having the repair bill :p
