Myself, I find it very fun doing Torghast, both solo and with friends, having 4 lvl 60 toons that I do it with, Arcane mage, Protection paladin, Windwalker monk and Discipline priest, the difficulty of doing it solo differs from class/role to class/role, but also your contribution doing it in a group…
Best things about Torghast, if you ask me is…
The best thing about Torghast is that it is not locked to a full group. You can do it on 1,2,3,4 or five persons, witch is great for casual players and guilds. Oh, we are only 3 friends online this evening, but we can still do Torghast together.
The second best is that it is not timed. You can do it in your own pace, witch is great for players who want to chill and not stress out because of a game, just relax after a hard days work.
The third best is that is is random, or quite random. You cant completely prepare for it, you cant study a youtube link over and over to learn how to do it perfect, heck you cant even do it over and over again to be able to do it flawlessly. The randomness of what floor you get, what powers you achieve and what bosses appear, makes every run different from each other, tactics will have to be adapted and the outcome is always unsure.
Worst things about Torghast, if you ask me is…
The worst thing with it is that it quickly becomes quite unrewarding. If you have gotten the memories you want and don’t need any more Soul ash, there isn’t really any point in doing it besides from having fun.
The second worst thing about it, is that it is mandatory. No content in an MMO should be mandatory on this level. Diversity to peoples playstyle is always preferred.
The third worst thing about it, is that the different instances is time gated. You can only do two of them each week, while I would prefer that all the six instances should be open every week.
Now I have gone through the pro’s and con’s I feel is important regarding Torghast, lets look at the solutions I think would solve a lot of issues.
Rewards.
Torghast should have a slot of its own in the vault. Lets say an 8 equals a Mythic 5 and downgrades from that. I also thing there should be drops from the mobs inside that equals overworld mob drops. Nothing fancy. Just some gold here and there, some resources and such. Also the last boss should drop a chest equal to Mythic with a chance for an item and some valor. (Yes all drops from Torghast should be treated as items from mythic regarding valor upgrades.)
To wage this up, Mythic and Raids should drop Soul ash, also there should be a chance to get a memory that usually drops from Torghast, as memories from dungeons and Raids should have a chance to drop from Torghast.
This way the game would cater to most of the playstyles that its players have. You can play the game how you want and still have a feel of progression.
Mind, that there should still be a reward for doing elite hard content like Mythic 15+ and Mythic raids, but to me the solution is rather simple.
Just have items like armor and weapons that are unique from these types of content. They don’t have to be extremely overpowered, but just a bit better than the tiers below. Like a set bonus that gives a small bonus to the characters abilities.
Just my two cents.
