Battlegrounds - Basic tactics
Please read these common tactics and battleground concepts - http://www.ticopa.com/wowbg/index.html
Feel free to convert this thread into open discussion about what/when is better to do in which Battleground.
My general feeling is that the majority of people playing battlegrounds are either ultra incompetent or afk and have no clue why they are inside the BG whatsoever. I've done well over 50 BGs on Lordaeron horde's side and I can tell you for sure that horde guys have absolutely NO clue what to do in AV, most of the times don't know what to do in EOTS (do not go for the stupid flag with less than 3 bases capped), rarely know what to do in WSG and basically give up and AB is the only "holy grail" where you can achieve approximately 50% win-loss.
