The majority of classes have bis from both because blizzard wants you to spend the time doing both.
People who do both will have an advantage over those that don’t.
You have to also consider how that fits into the context both types of content is done in, especially at a higher level.
Raiding is a race, the goal is to kill bosses as quickly as possible after release so you need as much raw ilvl upgrades as possible early on to meet gear checks of new fights and progress through the raid. This incentivises repeatable sources like mythic plus and, due to the nature of crest acquisition, makes crafting and upgrades almost entirely dungeon based until you’re already deep into progress.
Mythic+ is a ladder, the climb is gradual and the only thing that really matters as far as rewards is where you end. This puts the emphasis on fine tuning gear / acquiring the best items possible over a much longer period of time. Raiders including myself have said time and time again that raid loot, especially that which is obtained from later bosses, is barely ever relevant to progress raiding because you kill bosses like Tindral once during progress.
What we’ve got is two separate PvE game modes running on opposite timelines. Raiders need m+ rewards early on to supplement progress and m+ers need raid bis late in order to be as kitted out as possible for push weeks.
Neither side feels like their primary form of content is their primary source of gear progression and as a result they’re at eachother’s throats…
I don’t disagree, I don’t like them being intertwined either.
My post was just clarifying that despite this endless loot rain the content keeps getting hammered for, it’s not usable loot in any content that matters.
I don’t like that raiders have to m+ for crests. I don’t like it that m+ has to raid for 10%+/- throughput swings for trinkets/weapons. I don’t like that m+ groups are encouraged to run BRH until their eyes bleed on split runs to trade a Vers tank trinket in order to survive upper tiers. Edit to add the cheat death trinket, which is historically a raid item.
Lots I don’t like about the set up, but m+ is a far cry from usurping raiding’s throne. All they’ve done is take world objective/currency farms and shove them into the 16+ bracket.
I do Heroic raids for trinkets and special drops like the orange stick this season. Otherwise, there’s no point since I can grow my character’s power level through M+ at a much less restrictive (time-wise) pace.
Does M+ undermine Mythic raiding? Yes and no. Yes, in the sense that players who are only interested in grinding power upgrades (i.e. gear) now have an alternate path. Before M+, the only way to gear up to max ilvl was through high-end raiding. M+ has drastically reduced the pool of gear-chasing candidates who, in the absence of M+, would have applied to and been picked up by Mythic guilds.
But also “no” in that people who apply to Mythic guilds now are probably doing it because they enjoy raiding at the highest level so there’s an unspoken level of commitment there (at least until they jump ship because their current raid hit a brick wall).
