Blizzard, if the Horrific Visions are what we should expect from the Torghast, then you better to take care of tanks, healers and certain DD specs.

Horrific Visions (and Corruptions) have a few mechanics that favors Damage Dealers (especially certain on demand instant AOE burst ones) over healers and tanks.1) Its a DPS check content. Your DPS matters the most and survivability is secondary priority while also important, but DPS compensates it. Tanks and healers are way behind in terms of it and its pretty hard to solo the content that was by its nature designed for DPS.1.1) Corruption system is another problem - its also mainly DPS buffs, and while it helps tanks in some way, its not even near as good for them as for damage dealers, and certainly not that helpful for healers.2) Intensive pushbacks, stuns and knockbacks are also punishes all specs with cast abilities. While mobile specs can avoid it, its very frustrating and not fun for the rest of specs.And its not about "get gud". Its about the fact that those mechanics means almost nothing for certain specs, and heavily damages the gameplay of others. At last, its not fun to not be able to deal the damage, when you get stunned or thrown in the air every 4-5 seconds.Here comes people's advices - Dont do it solo. Get the party!No.3) Vessels mechanics. To get into the Vision, ALL party members must sacrifice their vessels. That means 2-3-4-5 vessels loss in case of failure.4) Difficulty scaling. Mobs' scaling goes up to 120% for 2-man party, and even higher for 3-4-5 man parties.That means that solo gameplay for certain specs are more preferable. At last, even if the people would like to do party-Vision, they most likely would like to get another solid damage dealer, rather than tank or healer, or heavy caster. Right now its clearly not profitable or effective to do Visions with 1 DPS + 1 Healer parties.Point 3 and 4 means, there is relatively low chances for a healer or tank to get into party, especially for a healer.Maybe it will be changed on higher difficulties, but(!) to get there healer must have already been equipped with solid iLvL cloak. Which brings us back to how to do it solo?Here comes people's advices - Respec into DPS spec.No.5) At this stage of WoW most specs have very different sets of traits, essences and stats.Asking to respec is essentially the same as asking to farm second set of azerite gear, some more essences and bis stats items.I can't call it the good design if to make MAIN (solo too!) content doable you force players to respec and farm twice as much as effective DD specs.God forbid Blizzard force players to do the same with Torghast.TL;DRHorrific Visions aren't suitable for solo healers or solo tanks or solo heavy-caster DD specs. Most people won't want them in their parties until highest difficulties where there will be not so much suitable tanks/healers. DPS checks only type of content favors certain DPS specs only and damages the rest of them and its NOT a well designed main content.Thinking of Toughast gameplay, Blizzard better either think of Mage Tower type of content that makes all roles equal, or not bring failure mechanics from Horrific Visions (i.e. remove Vessels requirements and tweak the scaling).
