I have read that killing gaurds of the opposing camps is a good way to get faction. Is there any info on how tough those gaurds are (that is, how many HP they got, what level should average druid try it, can they be kited effectively and if so with what spell line-up etc....

they summon and hit for 500ish iirc. never solo'd them as a druid (druid is a twink 59) but as a 70 necro they are cake to just tap tank. not sure on your level but im sure a 70 druid should have no prob killing them too.

I tank solod these guys many times while factioning for DoN.
