Yes i would! saves me from doing it manually
I have another idea too

You see it all the time, basically you set your character in a certain zone, and it will hunt down members of the enemy faction.
Like example:
if target isHorde
>> move towards
>> if Horde count > 1 & lvl90
>> run away
>> else
>> kill!
Basically, the alliance char flys around the zone looking for horde players, if there is one, it will check if there is any more with him and if it is are they level 90, else go and kill them!
This is basically what ppl are doing now, just flying around killing lowbies.
