My basic strat is to run straight for the flag but dont go all the way in unless the majority of their team rushes the flag. This allows me to basically stop them from running thru and controlling the middle.

Often times the other team will cap their two towers and then send a big portion of their team over to fel reaver ruins right away. So the start of every match leads me to the center on the road. I just stop there for a second waiting to see which way the BIG group of ally go, then i go there, starfall + typhoon + trees usually stops them cold. Then, if i survive lol, i continue on and cap mage tower, which usually gets the alliance's attention and they continually send their forces after me If they start going for the flag, my healer friend stays back at mage tower and i send my 4 boomers to the flag to help clear out. If my team is worth a shit then they defend fel reaver, and blood elf tower, and harrass alliance at the flag.

3 capping is the best route for me, zerging at alliance to bust them up first right away helps. Get them in a defensive mode.

The BEST and most important thing you need to do is to watch where the opposition is. Try your hardest to go where the majority of them are NOT. ie if they send 8 scrubs to blood elf tower then go cap another node farthest away from there. The more time it takes the opposition to catch up with you the easier it will be to pick of 1, 2 , 3 of them at a time before they get to you and wipe you out. If you can stay away from their large scale zerging and keep them chasing towers you're best off good luck out there!
