One thing you should know about the Curator's Hateful Bolts is they use the same mechanic as Patchwerk's Hateful Strike, they will go after whoever has the highest current health that is not the main tank, so assuming you at least get a HoT, they aren't going to be killing anyone. As such, I've never really seen the point in having a 'Bolt Tank', in the unlikely event someone has 5999 health (the max damage of the bolt), it's going to hit someone with higher health. As far as boss mechanics go, it's possibly the least lethal thing I've seen since well, ever. Maybe it could kill a Warlock or Shadowpriest that just nuked their own health down (I have seen Shadowpriests almost 1 shot themselves with SW: D on an evocate ...)

It was just too easy for me to get that much arcane resist not to do it. And while its not dangerous, I think it will make when I convince my guild to try kara with 2 healers that much easier. With 300 arcane resist (I just got the prince kill trinket to move me higher) I was getting hit with 1k to 1.4k.

On the subject of resists, what gear sets should I be picking up? I offtank in Kara and am starting to work Heroics.

Arcane if you feel like it (Curator)
Shadow is pretty much a must (Pandemonius, Zereketh)
And a bit of Nature and Frost (Hydross in SSC)

By the time you get to Hydross, I doubt you'll really need any of it though. We DPS the hell out of Curator, I've got enough health now that 1 healer can heal me through Pandemonius, I always skip Zereketh, And ... I'll let you know on Hydross when my guild goes after him again.

Whilst none of my guild uses Arcane resist for Curator, I have found it to be useful for some of the trash leading up to Curator, and just afterwards. Some of these mobs do arcane melee.

As for Hydross, has anyone here succesfully maintanked it as of yet? I know we may not be the best option for the role, but I'm still curious as to whether there's any success stories to report.
With Hydross's damage being reduced in the patch, we might have a better chance then.

Sorry just a point that Maratai picked up on, with regards to the spreadsheet I posted earlier. I have all calculations set to manual by default (don't ask why), so to get a global recalc across all sheets you will need to hit F9 to force the sheet to recalculate.

Alternatively go to Tools->Options->Calculation and tick the box that says "Automatic".

No comments at all? If people tell me what gear/enchants they'd like to see I will add them, plus if someone wants to try and correct my Attack Power formula that would be great.

I like the spreadsheet a lot - maybe add the top 4 or 5 items for each slot? Although this will change a bit in 2.1, there aren't that many viable alternatives for each slot from a tanking perspective.

I was going to ask about the autocalculate, but looks like that one was already taken care of.

There's an error in the warden's haulberk, though. The 39 strength should really be 39 agility.

Do taurens really have 1900 more hp than elves? And does that scale with gear, or is that a fixed amount? I'm starting to wish I was horde...1% dodge...bah humbug.

Yea it scales and yea warstomp > sm too. Only thing I have goin for me is my Alizee dance.

Right just to update, I've got a more comprehensive list of higher end gear now, I'm going through and basically adding a gear database to an extra tab. It's taking quite a while and is a bit frustrating but you get the general idea. I'm also trying to come up with a way to implement socket & set bonuses, but in the short term it'll just be a matter of having to tell the sheet whether you have set bonuses, and I'll be assuming that people socket stuff "as intended".

The epic gems are a complete pain in the arse - is there anywhere that lists them in an easily copy-able format? Otherwise I'll just leave a few lines for custom gems to be added, going through them all is going to make me cry.

Hopefully back with a new version by early evening.

I'd be interested in this one too, there seems to be a lot of anecdotal comments but nothing concrete. Getting high resist in two schools and maintaining enough threat to keep the mobs off the dps looks to be a an issue from where I stand.
