DISCLAIMER: I am just presenting my opinion here and the why I can't recommend this mod anymore for anyone that might play modded Terraria. I am NOT judging or blaming the developers, I am NOT trying to attack no one. It's just my sincere opinion about something I loved to play, but cannot play it anymore

I pretty much love this mod, Played it alone with Vanilla Terraria and it's pretty good... Alone...
I know this is a big mod and probably the development of it took a lot of work, but for me its a little abandoned compared with other massive mods.
I really like to play Calamity and other mods and Thorium specially because of the classes, but when put it together (I mean When you try to put thorium with any other big mod like Calamity) Thorium has lots of problems... Sometimes Classes are just broken, sometimes it's too weak for the end game the other big mods presents. Some items are good till the end game but there is no weapons or other stuff post moon lord for example (and most of the big mods add lots of new bosses post moon lord).

Sincerely I would LOVE to see packs that balance Thorium with other big mods. That adds more endgame stuff for Thorium amazing classes. But it looks like the development of this mods by the authors ended and I don't know if it's possible for other teams to work on it properly...

Sadly my only hope was literally crushed when I discovered that this mod had to be removed from the development of an amazing mod pack I was hoping could save this mod, re-balancing and creating contents for this mod to thrive among the other massive mods.

But sadly this discussion might be my goodbye for this mod and I hope someday I can find another mods with new classes well developed like the ones I loved here.
