not a beta tester but i was just curious what beta testers and people in general would feel are good numbers they woudl want to see from a tanking DK in comparable gear to a dedicated warrior/druid/paladin tank for tanking raids/10mans. The reasons i am not including 5 mans is that blizzard has stated they are balancing normal 5-mas to be tankable by a tank in DPS gear. I am talking about a tank in tank gear.
For example my level 70 warrior who has just started tanking kara has 12.6k HP, 12.7k armor, 12% dodge, 18% parry, and 21% block.
I would hope that a dedicated DK tank in equal or close to equal gear would have 17% dodge, 23% parry, roughly the same armor so i will say 12.7K armor and more HP so I will say 15K (now keep in mind that is a random number, however an equal geared DK should have more HP then a warrior but less then a druid of similar gear).
SO i was curious about others people thoughts an ideas, especially beta-testers, if you curious as to the reason why i picked those numbers i will give it.
