Sometimes it's fun to look back and remember the different bugs we had to endure when TQ on PC just came out. Many of these bugs were fixed in the fan patch but I'll just list what i remember:
1) deathchill aura - ravages of time did not work.. seemingly a very good skill from spirit is good only on the skill description.. but in-game, it does not give you anything at all
2) Triumph from warfare, another should have been very good skill, did not work due to bugs
3) Homados MI armor instantly maxes out your attack speed.. lolz.. although this is actually beneficial unless you're against cheesing
4) Hades' 3 high generals quest reward is 5% total damage.. very good... until you exit the game that is because the next time you reload, that 5% total damage is gone
5) Plague skill by nature.. this one i never got to experience or maybe just forgot but i read somewhere that once it was cast, it never ends.. there is no duration.. lol that must have been terrible
6) Pets including briar ward does not get difficulty bonuses.. Petmasters sure had a tough time
there must be more i just don't remember.. anything you can add?
