What you're literally asking is making the Normal and Alliance raids and MSQ for that matter HARDER. Which is a thing i've been saying that SE babied the shit out of their players. Let me ask you this, do you consider Strayborough first boss to be that? Because you just exactly asked for Strayborough difficulty. But good luck trying to convince most players "look guys, strayborough is a midcore content". And ive seen wipes to that boss where they have to reset.
If you're taking DRS as chess as a standard of difficulty, again I'm asking you. There are shittons of mechanics in extreme that are even below that level. Why would adding a body check (which most of extreme dont even use body checks but they used vuln) suddently makes it not a midcore?
This is not an argument of what consitute as midcore. Like my dude, youre asking for less healing intensive fights than extreme. Do you not understand the level of sloppyness you can get away in extreme? Sage can basically just spam shield and you would not even have any trouble mitigation or DPS wise
And let me get this straight, I dont consider midcore from just difficulty perspective as I've said. Difficulty is just part of the slider the devs can play. Extreme is a midcore content, because they slide that difficulty just a TINY bit higher, but they remove virtually any barriers to entry. You can clear it immediately after finishing story just with class gears and spend even a reasonable amount of times (1 hour to maybe 5 hours to prog at worse). I would actually even agree the argument that extreme is not midcore because the grind for the rewards is not even comparable (clearing 100 times for sometimes a shitty mount copy pasted, how fun).
But you're impliying that Extreme is already hardcore territory because of body checks are kinda indicative of why NA parties are struggling in CAR.
