Decided to post up BG tactics as this is what I mainly do. Thanks to Kurios for advice on what to post on the site. Works for anything below level 40.
You will need a pally, warlock, preist and shammy. ANything else is a bonus.
First off, you are going to make sure the shammy is down the bottom next to the flag. Have him set Earthbind Totem and Searing Totem.
Have the pally, lock and preist placed up the top (balcony in WSG, the top one so its hard to get to you) in wait for the attacking flag group. The group should almost instantly move on your shammy. Thats fine. Have the pally bubble him and have the preist move out of your line of sight to bubble the lock. Now let your lock send in his minion and DoT the crap out of everyone. Casters may try and have a go but they should be dead/your lock is bubbled. your enemy should have the flag.
Get your pally to run down and stun before the flag runner escapes from earthbind. Have your lock DoT him and fear anyone who attacks, and your preist healing and using pots for mana. The attackers should be devasted by now from the DoT's from the lock, the shammy fighting (you must keep bubble on him at all times) and the pally should have stopped the flag runner. Hello to honour/flag returns and winning bg.
Hope that helps, feel free to flame if posted before.
