Not yet, I've been mostly playing Calamity, going through normal, then expert, now master mode.
I don't really like where Terraria went with some choices. Shimmer is too strong of a mechanic. It feels like one of those things where people say "Just don't use it." But it feels wrong not to.
Pylons were a full replacement for teleport networks which have now been relegated to only be for combat.
Reaver shark used to be a reward to give you something strong for doing something for a long time, fishing. It doesn't break the game especially since Molotovs can just teleport you into hardmode faster than Reaver-ObsiSkin potions did.
