On my healers which are similar in a lot of senses similar to tanks, here are a few things to consider in relation to your post.
First, my healers are on a half dead server with very limited guild options. My main option for group content is to join any number of guilds that have an average gear level that is about twenty or thirty below mine and run normal raids once a week when I like to raid nearly every day, and have almost cleared Heroic already. The same goes for running mythic keys.
Second, I can server transfer, but on my two connected realms I have a total of twenty eight characters I would love to transfer to Proudmoore and/or Stormrage for more options, but I am not paying in the seven or eight hundred dollar range so I can get my toons and their synergies working for me.
Third, I do do cross server things in a community but Blizzard has given people like me the short end of the stick when it comes to doing Mythic raid content that one of my toons is already up to speed to tackling. I will be shut out of that next week and for a few months–another reason I feel shafted.
Fourth, the above means I am either forking out hundreds of dollars to do switches to a high pop server where I can have access to groups or I pug.
Well, Blizzard just wants my dough, so they set the system up this way and are not going to change. You can join an overfull server for access to group content with a regular group or you can suffer through the slings and arrows of pugging. As a healer, I get blamed for a lot of group fails in dungeons, generally speaking. I regularly get hammered because people die, and yet there are groups that run dungeons with NO healer. The reason people die is because they don’t know how to dodge, don’t know how to interrupt, and don’t know, for example, that in some fights the damage is reflected back to you and the healer can’t heal you through that.
Now, all of this in mind, as a healer, I now have to contend with Blizzard’s new Horrific Visions being completely “horrific” and unfriendly to my healers.
My choices are as follows:
a. Struggle through Horrific Visions and die over and over, and just be perpetually frustrated with the whole thing. That or learn in a day how to not only to play a dps spec, but play it well. I’ve tried a run on my monk healer as dps spec after reforging my armor, setting up my ui for dps, buying weapons and doing runs for trinkets. Well, that ended quickly and badly as I am used to playing her while being able to heal myself, and like to know my healing characters inside and out without always having to switch back and forth–which also, consequently, is costly having that you either play with your best armor reforged day in day out or you play with your lower ilevel azerite armor. And let me tell you–reforging three pieces of armor on a daily basis quickly adds up to in the thousands of gold range. Anyhow, the run was a huge waste of time and effort–the daily visions are also sometimes a hassle on a healer. I often have to run around the perimeter of the area to avoid long fights and aggroing more than one mob. I am also used to dpsing on her as a mistweaver, and havent played her dps spec for a couple years.
b. Try to pug them.
c. Unsub, and just forget about this patch.
d. Play other toons–basically dps characters like my warlock, and/or new Mechagnomes. And just add to the already out of whack imbalance of more dps and less tanks and healers.
e. Play Steam games. Play another RPG. Play Electronic Arts, Xbox, Sony Playstation games.
f. Watch Netflix flicks.
g. Do something productive like read a book or hit the gym.
