Skill level necessary to clear HW MSQ content

[Hasrat]

Sounds like it's not so much skill you need, just time to learn mechanics. That's not strictly something that "carries over" into MSQ or anything.

Gearing up is all well and good, but most of the HM content should still be clearable without much trouble even at those levels, considering everyone else is fully capable of carrying. If you're going in as a first time healer (with middling gear) to a fight you don't know, yeah, going to be a fair bit of trouble. Learning a fight while also keeping up with heals is just bonus stress. You've got the added difficulty of heals not being as strong as they could be. But, with the benefit of a second healer. Just, let the group know you're new, and hopefully partner healer can help pick up some slack while you learn the fight.

Again, would say that there's little skill to gain from harder fights. It's less about skill, more about mechanics. If you're unprepared for a mechanic and get hit, you'll start to learn how to handle that mechanic. But it's not strictly something that translates to being better in anything else. It's the same game of "dodge the telegraph." You can learn how to do that in Sastasha as easily as you can in Coils.

Also yeah, queuing into any EX or Coils is unlikely to get you a group for a considerable amount of time, and even then, likely to be a group with a steep learning curve. Running that content synced is something not often done anymore. Because it can be difficult juggling all the mechanics of each fight for everyone. But, those are fights far beyond what is run for MSQ.

As an example, you can fight and learn and feel skilled all you want, but that doesn't strictly mean you'll instinctively know how to handle Leviathan's mechanics when you get in. That's just sorta something you'll have to pick up as you go.

All that said, if you still to run the fights, synced or unsynced, go for it. Tho, I guess unsynced is probably more of a zerg these days than when I ran them like that pre-4.0. Still. They can be fun fights to learn. Just, expect to die a bit for them as well. Gear still counts for something in those fights either way.
