It would be cool if we could make it work, but damage shields are bad for trials tanking because they are un-mitigated. Not affected by your resistance or holding block.
So, if you have 70k health and a 50k boneshield....one or two hit from any trials boss and your shield is gone. That's why they are bad. BTW, none of the damage shields are really cheap to cast and can't really be spammed.
I would also like to add whatever nonsense you read about max resistance not necessary is simply not true for learning in Vet Trials setting. With phenomenal healing and other mitigation techniques cough GUARD, you can get away with less; but when learning do your group a favor and wear Maxed resistance sets.
I also use shield play enchants on jewelry. Some recommend magic recovery so you can spam igneous. This doesn't work so well for learning my Redguard DK. 3 Block cost reduction is much more effective. For magic tank to work you need blue Wrothgar Health/Magic recovery food, attributes/armor to 30k health, 20k stam, rest magic.
The Meta Builds you read about work well with Meta Groups. They are tried, tested and true. That said, I've seen the Meta cause much frustration from groups that aren't optimized for it.
See, high end groups that put this stuff out there like it's gospel don't even take any stam builds in with them. Console is quite different. Often times, more than half the group is stam build. Maybe adding Hircines would help group more than other healer sets.
I had a night of frustration last night; 2 Vet HelRa, 1 Maw. none passed. First, tank had some Tava, Alkosh, Bloodspawn build kept dying at air atronach running out of resources or getting one shot. Got down to even 2% health and the group wiped. After few attempts called it quits.
Maw, couldn't beat the first boss.......not uncommon. Kind of knew it wasn't gonna work as it took so long to get there.
I tanked the last HelRa all the way to the warrior....couldn't pass the DPS check from 70~30% the adds needed to die much faster IMO.
Some other thoughts:
I've seen very few groups that can beat the top boss Flame Spinner in HelRa.
It is super rare to see anyone using maelstrom or Master weapons on console.
I don't even need anything in these trials but weapons. I give it all away. This is for fun mostly.
Eternal Yokeda is terrible reward for such hard content.
