Apologies 1100 is ok for Jump, usually 1050 - 1150 is decent if using life surge with jump? For some strange reason
On topic on my alt with full crafted Mage acc. I think it's important to get vit iv in 1st and put another vit I on the end for 9 vit, yes it's only 1vit for a meld slot but the only reason u will be using crafted accessories for any period of time is for the vit increase, so why not maximise it.
I only speak from experience of my alt whm clearing twintania in full dl and crafted acc to make up for the hp. Unfortunately whm doesn't have a gear requirement like the dps assuming a decent tank as long as the hp requirement are met, 4.2k in my groups case
