I can't remember who wrote about it :S so sorry if I'm stealing someone's strategy here. The Idea (especially with lower lvl BGs) is to rush through to Stables/farm (I know, I usually hate ppl that take stables at the start too :P- but with mboxing you need a different approach to everything) and cap it.. if you have one or two ppl follow you even better to some extent (as you have no healing :S)

So if your are horde for instance.. GY.. rush to LM then onward straight away after you take everything out to stables.

Whilst the rest of your team is busy killing the opposing team, half of the enemies are likely to res at their GY not stables/farm.. you now begin pushing them back, whilst the rest of your team play catchup and take the rest of the nodes. Just make sure you really put the pressure on, and go absolutely ape doing as much damage as you possibly can. The idea here is to give your team enough time to cap nodes and move forward.

Best idea would be to ask a healer or two to help you.. although be sure to take some enemies out on the way to stables/farm as you don't want them to go around you completely.

I haven't been able to try it out myself yet (as I'm doing BGs exclusively when i hit lvl 59), but supposedly it works rather well. especially when ppl see you killing like crazy. they just want to move on up

EDIT: a shaman team should perform remarkably well here. the combination of 4/5 shammies +a healer, healing whilst you dps your heart out is insane.. Siege cannon anyone? this combination should easaly handle a constant stream of enemies, even if there are several at a time, simply because they die before they can do anything.

Even if you only take out 3-4 on your way to the stables it should prove successful. the rest of your team are bound to kill some others before the opposition takes their first node, so you should expect roughly half the enemy players to be rezzing at the GY. at this point you just need to keep the pressure on and not allow them to make any headway.

They will also try to recap their lost node, so you should see just around half if not a bit over, returning to the GY/initial node, and thus to their deaths :P
