Tanking raids are super simple, tanking m+ is far more complex, well if u wanna do high keys, u need to adapt to new routes very often, also u should be confident and lead the grp, also know what pulls is ahead and speak in voice etc. tanking in raids = just tank taun rotations and placement. pretty much the most easy thing u can do in wow.
Tanking in raid is IMHO the most boring experience. By that, the strategy is all aboot switching active tank every 30s, ie when boss hit you so hard that you can’t afford being hit by such ability again.
Now M+ tanking is on another level.
Firstly you’re expected to know the latest trending route. They sometimes completely change the route, so be ready to often change routes.
Then you’re expected to know how specs are dealing damages. For instance, you would want to make larger pulls if your team has a fire M+.
Also, you’re expected to know what classes bring, more especially yours. Since you’re posting on a warrior, I guess you’re a warrior main, so You’re expected to know which spells are being dodged while using spell shield.
Lastly, you’re expected to know covenants interactions.
Tldr : tanking in raid requires no other knowledge Than your class whereas M+ is more demanding.
As others have said, in raids tanking is relatively chill. In M+, you’ll have a ton of responsibilities, but you’ll also be able to get groups very quickly.
