I've encountered a game breaking talent specialization bug. Yay! I boosted a mage with my "free" boost, logged in, immediately tried to change my talents aaaaannnnd it's broken. Literally. I kept getting an "unable to apply talent" error so I imported a tree (from Icy-Veins) to try to work around it and now my shit is fucked. I was able to apply the talents, but now the game is treating my character like I have no talents at all, and I cannot reset and rebuild the tree, receiving the same error as above. My Frost spellbook is empty; I only have general mage abilities.
Fire and Arcane work fine and I can modify their talents, but Frost is just broken. No, it's not user error. I have tried literally everything from re-installing to repairing to deleting/restoring my toon to restoring the starter build...it just doesn't work. And, again, other specializations work and I can change talents in them to my heart's content. I'm just permanently locked out of ever using Frost until they fix this. There is a large thread in the bug forum documenting the issue. I am not looking for advice on how to fix it; it cannot be fixed. I am just here to vent and warn people away from this disaster.
I can't believe I convinced myself to give Blizzard another chance. I can't believe I spent $70 on this garbage fire of an expansion.
