Palakaii is my brothers toon, he's well geared but not amazingly geared, lots of KZ runs and some higher stuff. He would run in, gather the entire bottom level of the cathedral, then stand there and consecrate/holy shield it to death.

One thing I did was throw flamestrikes or blizzards into the mix as it got lower so I knew I wouldn't pull agro, a few times I did pull agro and bam, dead.

Palakaii had to bail to play with his roomate on another server, so I borrowed a guildies pally, much lower gear:

I was actually 5boxing with croll, made the strat of follow the pally a lot more dangerous... so I would park the 4 noobs, and pull the lower level with the pally, repeat for the upper level and then do the cathedral in 2 parts.

Important things to note:
Wizards have a flame shield, this does squat to the paladin cuz he's 70th, this will DEVESTATE level 40's quickly. You pull 15-20 mobs, 4-5 will be wizards with their flame shield up... ouchy!

Don't flamestrike/blizzard too soon, it's painful.

FFS don't bubble... I fatfingered bubble once... everyone died very quickly and the paladin was all lonely...
