They could do the new accessories to be similar to how the current pentamelds run, a split between VIT and the other main stat. I know the statement was made about end game crafters being left out, but tank classes are the only ones using them for end game raids (not counting food/pots) so that argument is not very compelling and for another forum.

A straight VIT based damage formula would be flawed - the highest VIT achieved on a Paladin based on gear alone is over 1110. Strength cap on a DRG is 1070 ish. Without a near complete rework of skill potencies, buffs/debuffs, the fact that tanks would have a ridiculous amount of health and still put out the damage, and the non cookie cutter fact that tank gear would be the only class with 3 stats on it, I just think it's too much actual work to do for the devs (says the guy with no programming experience). Yes, it would be possible, but wouldn't it be easier for SE to use the existing damage formula -changed to the new stat - versus doing a complete to rework in order to account for more available VIT?

The only way to prevent tanks from using slaying gear would be to either:
1- make it unequippable (won't happen)
2 - Change the tank meta to turtle meta (and lose many DPS to tank converts in the process, and could cause issues in current end game)
3- Make strength worthless on tanks and go to VIT (possible - see above)
4- Come up with a Tank Specific stat for damage, convert strength on present left side gear to the new stat, AND put it on the accessories - just like the Ninja release (because SE hates following the same pattern they have already done before)

TL;DR
New tank stat is easiest
