Saraie,

I am running a team of 5xpaladins who are also 80th level. I am in the exact same boat as you are. I used BS to get my tank the purples in helmet and boot. I also bought purple leggings from the AH. I used all of the gem slots to up my defense to 535 as well as any enchants that do the same. You can get a shoulder inscription from the Sons of Hodir quartermaster to raise your defense as well.

This is what I found out. Most of the people who box heroics use teams that overgear the instance. Their tank outgears the instance greatly and the dps are hit capped and use a dedicated healer. What I am doing is running dailies to make gold to buy mats to make purples (or just buy purples) so I can run heroics. This takes time. I have cleared UK heroic up to Ingvar. I have cleared Nexus up to Teristraza (sp?). I can clear the old world raid Karazhan minus the bosses (I do this for gold).

There are a few people that offer geniune advice here. The rest just offer a brag sheet. The real path to clearing heroics is to outgear it. And you do that by making the gear, buying the gear or just farm honor and buy the PVP gear. I have done all three and this does take time.

By the way there is no such thing as boxing 25 dailies in 90 minutes. The most I have been able to do in 90 min was 18 and this was with the very easy boxable ones. Most of the time it takes me 2.5 to 3 hours to do 25 dailies.
