I played BotW a lot, and really loved it. I feel like the beginning of the game was relatively easy compared to TotK, I died a few times trying out things, discovering the game and possibilities ; in TotK I died a lot and still do even with good gear and armour (1*-2* armors, 30-40+ damage weapons). You could say it’s skill issues and I would agree with you as I am not a pro player and play games once a week maybe, however I feel like the difficulty curve is far greater in TotK. That has affected how I view the game to the point that sometimes I think I dislike it (even though the new powers are the best thing they could have added, with the verticality of the world) ; that might also have to do with the much darker ambiance of the game, which can feel frightening (to me) to the point going underground is hard.
Is it just me? Should I just “git gud”?
I think the sages are the biggest thing here. The bad guys don't typically do the thing that games like Assassin's Creed bad guys do where your may have a gang of events but they're roughly taking turns coming at you. In TotK, they're just all over you constantly and the most effective way to keep that heat off of yourself is via the sages.
