Yeah, leaderships works great if you have people that listen. I rarely try it, especially in AV, but EOTS and AB I tend to talk more. What's your general plan of attack? I find if Group1 and Group2 go D in front of the keep at the chokepoint and dont get zerged it works great (I'm in this group many times). This relies on the alliance not zerging and coming in with a stream of attackers once their first GY has capped, otherwise you create a turtle (which is why I dont think horde should kill anyone until the alliance caps a GY which means the best defense is at the keep IMO).

This is my proposed battle plan for AV:

Group1 and Group2 - D at keep
Group3 SHB
Group4 SHGY
Group5 IBB
Group6, 7, 8 to Bal.

Once Bal drops 6, 7, 8 continue to SP. If it falls easy they can push into the alli keep area. If they wipe they'll spawn back and should be able to reunite with groups 3, 4, 5 whos stuff should be capping about now and can 6 group zerg as an offense.

If Groups 1 and 2 get pushed out of the keep their sole job is to get their midfield towers back (assuming they havent capped yet). If they have capped get a GY back in the south and try to push in to the keep area to snake the towers back or generally harass.
