For example, every single mage item (except for "Wrath of wraith" and "Mana dagger") is worse than vanilla counterpart and it often takes much longer to obtain those weapons.
Also by grinding I mean INSANE grinding, like in almost every Terraria run I try to obtain Rod of discord as soon as I can and it takes a while, but Tremode items are 10x as bad. If I want to summon the Brutallisk I need 5 Cluster shards that randomly drop from random bags in few numbers THEN I also need 8 Phantaplasm which who the
knows where they drop from. Then after you grind for ~2h hours you are met with a boss, unprepared and not knowing his moveset, that almost instakills you when you are wearing the best available gear and you have to do everything all over again.
That's insane.
