Tanks will be necessary for raids to hold aggro of the boss. Toughness seems to be the only deciding factor on who the boss targets.
I see two sides to being a tank. Warriors and Heralds seem to be the better choice for heavy armor tanks as they already have high health pools and decent mitigation while guardians have good mitigation and low health pools. The only trade off I see for taking a Guard over the others is that they have access to a generous amount of passive mitigation in the form of regen and protection. Before many of you make an argument for aegis, do know that there are many small instances of dmg that break aegis before it can be useful and the timing needed to make it useful is not always reliable.
I have also heard of reapers being fairly good tank/condi dmg and being able to rely on death/reaper shroud takes some pressure off the healer.
Gear
Disclaimer ( i am in now way a genious of build crafting, hence partly the reason for opening this topic)
With thoughness being the main stat, I’m assuming that it can be made up in food and trinkets. This would allow players to keep zerker or other high dmg gear with a toughness minor stat as to not lose too much dps from the raid group.
I’m looking at soldiers and possibly sentinel’s gear (if you take zerker trinkets) to be the main stat combos for tanks as they offer toughness and power. Knights gear is also a great choice to proc many on crit sigils and traits that cant be made up with consumables.
I have also heard that Dire gear is also very popular for tanks that run condi specs(reaper/necro/possibly mallyx/engi).
Commanders (power, precision, toughness, boon duration), one of the new stat combos also seems to look like it might be popular. It will offer less toughness, which could mean taking soldiers/knights trinkets, but still offer decent power. Alternatively condi tanks can run tank gear and trailblazer (toughness, condi dmg, vitality, condi duration) gear to help keep up attrition.
Runes/Sigils
As little as I have looked, Runes of the Scrapper seem to be the best choice to a tank with the 7% reduced dmg set bonus as well as giving you additional toughness and power.
Sigils seems to be much more personal choice as many of them don’t really interact with a tank unless your a condi tank allowing you to various condi uptime sigils. As for me I see: intelligence, energy and concentration sigils being good for mitigation, boons and on crit traits. Alternatively if you are playing a a tanky/healing hybrid sigils of renewal might be useful as well.
I don’t see too much value in sigils or runes that remove conditions as the raid encounter doesn’t seem to apply conditions to you or allies (at least from what I have seen).
As I see it, Warriors, Heralds, and Necros seem to be the best option for tanking as they have high health pools and can still pump out decent dmg.
Engies I have heard can tank, but I have little to no research or knowledge about them.
Guardians having a low health pool but good mitigation I can see being used to re-leave the pressure from the healer, but they offer far lower dps.
I would love to hear/see everyone’s opinions and builds for the new raids as I intend to try tanking for my guild in the future. This could be a helpful discussions for the community to better understand tanking as well. Post not only builds but also helpful tactics and advice.
Also if anyone knows about mallyx revs for tanking and condi dmg I would love to hear it. I think it would be a very cool tanking aspect but last I heard mallyx was nerfed pretty harshly (if only in pvp).
