It was a letdown from beginning to end.

Let me start off with the positives, Its a big modpack and they tried make a fresh new experience with classes, combat & adventure.
Now lets get to the negatives, they tried make a fresh new experience but ruined it by overhyping it, overmarketing it, making false claims about how long it took them to make it, released it as a just a throw everything at the wall and see what sticks, it had and still has very bad performance, and every update through its life cycle the devs just seem to be removing anything that is remotely fun, removing whole systems and mods from the pack that where the main parts of it and then on top of that nerfing anything and everything else. And please dont even try to add other mods to this pack its so unstable, it will break your world, full stop. Even at the time of writing this its latest release still has major mods within the pack bugged like hexerei and the dowsing rod because they messed up the implementation to view the item in
first person, quests will just stop working, lag spikes breaking main quests or the AI for bosses just randomly stop or maybe a main boss just stops taking dmg at all bug, bricking your world ect ect. Back in its initial release it use to have ars, they nerfed the hell out of it and then nerfed it some more and finally just removed its implementation altogether like what? The pack from release to now has never really been good. There was a lot of hype right up until it released and since then it has just been letdown after let down. Do yourself a flavor and skip it, playing for 25 hours just to get a bug in the main quest isnt worth your time.
