Give me a fn break.
You kill tunare similiar to the same way you killed innoruuk with a bunch of lvl 50s in indocolite and yks only now you got better resists and gear to be able to take the punishment and ressing for a long fight.
Tunare probably has 1 million hps. This sounds like a very large number to you guys but you have to realize something...
If you can deal damage and keep yourself healed without effectively losing mana, then you can kill anything... just takes time. This is the way you will see The Sleeper killed, this is the same way you will see Bristlebane killed.
You also have to realise that Tunare will either be slowable or have lower hps than estimated.
Death touches will be dealt with by clerics with epic weapons standing just out of range to run in and click res the fallen comrades 30 seconds after they drop.
The biggest problem you will see is going to be that everything that has not been killed will zonewide agro, including the usual protectors of growth.
I estimate that people will kite any guardians for the duration of the fight while the majority of the masses are concentrating on tunare. Only time will tell, but I'm pretty sure this is the way it will go down.
P.S. Kinda looks like the lady on the everquest pics. /shrug
