The funny thing is, min-maxing implies all else equal. As in, everyone is equally as good as the mythic or heroic parse they're comparing against, are comfortable in that regard, and have the time to acquire the gear for swapping regarding bosses. Not many people are as good as the top-parsing raiders. I definitely am not.
I still parse though. I like to see potential maximum DPS. Does that mean I'm going to go the best build if I'm much more comfortable on another build? Or does that mean I'll choose x Covenant because the skill it gives boosts my DPS by 1k? Probably not.
Blizzard just has to differentiate choices better. Maybe one Covenant is better for AoE. Maybe one is better for Single Target. Maybe one is better for your healing spec. Maybe one is better for your tank spec. If they do this, yes, Mythic raiders will be pretty pissed having to do every Covenant to have access to them, if that's even how it works. Otherwise, all of us plebs will be enjoying choosing our Covenant based on the content we do most.
You'll always get the elitists who won't let you in a dungeon because you don't have a certain Covenant, or hell, because you're a certain
class. Bring the player, not the class needs to be a thing via balance, and Blizzard falls short here sometimes. We can only hope the class and skill balance works out well, or is at least varied enough so it's
FUN. If a skill is less DPS but FUN AS HELL, good luck choosing...
People forget that raid parsing isn't the same as dungeon parsing, or PvP, or doing old content, or doing the new Tower. If people can't see that not every skill has to be about top DPS, then they're not understanding what the World of Warcraft is. It's not WORK. It's fun. Yes, I know the irony via my name
