Part of why Bloodprice is where it is now is that SE is avoiding incentives for any tank to be the "Default MT" or "Default OT".

Back in HW, DRK was the default tank. Not 'only' because of its superior magical mitigation, as we know it was/is barely ahead of WAR while miles ahead of PLD who couldn't block magic at the time. But because of the massive DPS it gained from nigh infinite MP from BP + BW access along Reprisal and Low Blows procs which DRK completely loses access to in the OT position.

Now each tank has a negligible DPS increase that barely offsets the DPS loss risks of being a MT, PLD has Shield Swipes, WAR has Vengeance counters, and DRK has TBN.

For PLD, swipes are barely 3.5 (210 potency / 30 seconds iirc?) potency a minute which can still be fished for by blocking AoE magics from the OT spot, which, to be fair, is a very good use for that gauge that fills faster in Sword Oath than Shield Oath.
DRK can use TBN on others for an even easier shield to break (5k instead of 10k at current gear levels) for more Bloodspillers which are possible DPS gains.
For WAR, Vengeance isn't much of an incentive to trade off Deliverance for enmity.

Now you just stick the tank "player" that is more comfy with MT to the MT spot. If anything, PLD and DRK have as much incentives, if not more, to OT as it is than to MT now.
