When you're defending 2 points rather than the one in the middle? We split so we had 2 people at each conflux and 2 covering the centre main strip. The guys at the side focus on the two side spawns. It's good to keep one guy behind the conflux so you can always see whats going on. The teleport can get through if you don't. The middle guys go in front of the two main pillars on either side cleaning up the centre spawns and helping with cover fire of the "side doors" where the hidden oracles are later.... It's useful to have a sunsinger there to spam grenades when all the fanatics are spawned. The same tactics pretty much apply for the final bit of this stage when you're covering three confluxes too, just the middle guys fall back a bit. Lastly make sure everyone falls back to the middle after the three confulxes are done. There a big wave of ads and you'll wipe if you don't all take them together. Also, keep out of the green goop! :) Hope this helps, Dom
