How to get 300k damage in a BG?

[Littleburst]

I did this in an AV somewhat by accident on all four of my shaman.

You just need a slightly drawn out game and you need to play where there are a lot of alliance. I actually ended up in a long base turtle where I got to blow EM+TS a few times in a group of about 10-15 alliance-- that certainly helped.

I think I ended up with over 370,000 damage on my lead and 340k on the rest.

This.

Defend balinda, try to turle the game as much as possible and Farm HK's in defense. Just lose SH and IW so you got a good gankspot next to IW bunker. Kill all horde that comes by, then eventually you'll have a big battle between IW and Balinda's bunker.

If you sign up with 10-20 people who don't contribute to the offense at all you'll surely get a craptastic AV to get you damage done. ^^
