My guild can beat Jek'lik, Venoxis and the Bloodlord in ZG. It is very class dependent for Jek'lik though. You need at least FOUR mages in your 20 player group to beat her properly. Put your mages at the front with 1-2 healers at the place the bats come. Get you tank to fight Jek'lik around the tree. Make sure eveyrone is spread out and that your Hunters use Viper Sting, Warlocks and Priests using Mana Drain to get Jek'lik's mana down ASAP. Then spread out in Phase 2 so the fire bombs don't take multiple people out at once.

ZG is gear dependent indeed. We can get Thek'al to Stage 2 but once he goes Lion Form, everyone is out of mana. Mar'li is really hard at the start. We managed to get Jindo down to 55% on our first and only shot so far. Considering Jindo is the hardest ZG boss and not Hakkar, we might be able to beat Hakkar, since he is the one boss that guarantees 2-3 epics.

Good work on downing her. Venoxis is far easier than Jek'lik. Just make sure you have Druids hibernating the adds and kill them quick. Only have the main tank within range of Venoxis's AoE poison burn spells. As for the Bloodlord, have everyone except melee classes on the ledge so he can't charge the clothies/healers for 4000+ damage because the spears block the way. And if you're being watched by him, DON'T DO ANYTHING or he will charge you. And the more he kills, the stronger he gets, so don't die against him. Then you might be lucky enough to get his epic mount.

Hear about the anti-AFK out of battleground measures in 1.9? Apparently if you AFK out, you are banned from entering any battlegrounds for 15 minutes. That is a good idea IMO.
