I think there is a huge disparity in terms of player skill expression that is partly the players fault but also blizzard’s fault.
While better UI expressions can be achieved to give proper feedback, the talk of addons is another topic entirely.
So here just want to focus on bringing back something we already had but in a more pronounced way the MOP style proving grounds.
You take the basic idea of a delve which is more exploration based with a few checks do this or that interaction and a boss to a more skill-based experience based on your specific class.
I won’t list out all specializations, but they need to be paired down to styles of damage tanking or healing and then have their proving ground adjusted to them.
The zone assets or whatever can vary as well as mobs so won’t expand on that for now.
Damage proving ground scenario for following:
AOE, Cleave, ST and finally one that incorporate all three in a single player delve like scenario but with benchmarks.
You provide a separate 5th proving grounds with crowd control focus with minor mix of the three others.
This way you force people to practice their rotations and adjust. The difficulty can be scaled by the player.
The idea is people learn their specializations which means blizzards needs to be clearer about what rotations should be in a general sense as they designed them. I don’t even know if blizzard fully knows the ideal rotation for many specializations.
When people pick a specialization, it should be clearer what the strength are and how to play as those specializations.
Ok I am a resto druid so rolling heals over time is my bread n butter. Maybe a warrior tank with greater active mitigation is better to pair with my skill set.
Ok I am a holy priest, maybe a tank with whose health spikes more like a blood dk pairs better with my skill set.
I am a fury warrior, generally small area of effect but heavy bursting cleaves.
Most players only COPY when they see others due forming the meta but don’t know why its meta all the time.
So yeah, blizzard should implement evergreen content that focuses on spec performance in varied scenario. I think delves and even Follower dungeons are a good example of low stress low impact style game play where people can learn without being judged.
