Ok im making this thread as a suggestion if you like it please say if not fair enough.
For One or two nights all experienced burglars that come reguarly to the ettens co over to creepside, roll a warg and join a wargpack led by one of the higher ranking wargs E.g Murderous Mimic Dinkir or lilysnap.
Watch there tactics watch how they move, how they assist the raid.
In my opinion Wargpack tactics can easily convert into burgpack tactics with some time.
This will greatly help the way burgpacks assist the raid.
In the past when playing on the creep side i have known a raid to be in tirith raw fighting and a burgpack to be in EC killing a group of 2 or 3 freeps, this isnt what should be happening You should be holding the gate stopping creep reinforcements for getting up (like wargpacks do) or getting behind the raid and getting stuns/addles on the warleaders (Wargpacks do similiar only with silences)
Hopefully you will use this suggestion and it will help balance the moors.
Tuff,
