this is only supposed to help atleast somehow making battlegrounds. it wont be possible to navigaete only to run a pattern into the open battle.
as for now only warsong and darkmaul is done.
que a warsong. type /click warsong.
after entering the battleground dont do anything yet just type twice
/bat start
it should say now depending on your faction where to turn to.
you now type /oc without a number or bind it. wait for the tiny click sound after every turn to be sure the turn was completed. 
then you start moving only straight.
when you hear a coin collect sound you immidietly stop really fast.
when you died you target the spirit healer and type /bat to get instructions. (his name is alliance spirit healer)
in case you missed that while beeing dead or the rezz was too fast write /bat ws (this might only work in ws as the graveyards are always the same).

if you interacted or moved in any way other than straight lines this will result in all information beeing useless.
you then have to ignore further insturctions it just thinks you are on track as in battlegrounds there is no way of knowing that you arent anymore.
there also cant be any rescue points as that information is not accessible.

notes: 
best results are when you are just running on foot. walking will definetly scew it instantly and mounting is considered but not aura of crusader and stuff so be carefull mounting.
for warsong as alliance when you died you could aswell just type /oc 4.82 and run in the open. On hordside you dont even have to type anything.
i reccomend while in que do a /oc 1 to setup everything becasue the first turn is often the worst after a restart.
