How much max health do tanks have?

Ive seen some ogre wars break 5500 without vp gear and without tossing on hp focused sidegrades.

should Paly be using Black Sapphire Plat Neck over Symbol of Marr?

If you're a dwarf paladin, I'd go with their 10ac/6sta/filler neck.

Given what we've seen of AC parses, I'd lean toward the BS neck over Symbol of Marr. Also, keep in mind the whole 'AC being good' movement didn't really occur until:
1) CHeal was no longer a complete heal.
2) CHeal was abandoned in favor of multiple Light spamming.

The concept of effective health through AC isn't as true to EQ as it is other games where the effect of armor is not subject to variance. Before #1 and #2 happen, your goal is to be able to live until CHeal hits (survive damage spikes as opposed to minimizing damage taken).

I'd ballpark something like 1 AC = 3 HP over here.
