If A4 continues to have a magic tank buster on a 60s recast in savage I'm pretty sure DRK MT is gonna shine.

Pld can at that point rampart first, sentinel 2nd, rampart 3rd and blow hg on 4th (assuming savage gets to this point, I've never had more than 3 in normal). While drk can do the same thing except for the HG part but combine every one with an extra 30% mitigation from dark mind, taking a lot more stress off the healers. With delirium, shadowskin and dark mind I think I was taking roughly 2.5k per blast, less on shadow wall.

That is the beauty of the drk magic mitigation toolset, the ability to combine it with the other cooldowns which are almost the exact same as pld cooldowns (10% less sentinel vs shadow wall) since dark mind has such a low refresh. Would be tougher on something like twintania where death sentence had a 35 sec recast, but that was originally meant to be a tank swap anyways because of the healing debuff.

Paladin essentially has the same thing but with sheltron on physical busters, I'm not sure what a big shield mitigates at 60 (my pld is only 56) but assuming its 30%+ paladin will be able to combine their cooldowns with sheltron and take a ton of stress off the healers.

As it is currently balanced a good MT will be able to switch between PLD and DRK depending on the fight, while WAR is still by far the king of the OT role.
