TL;DR
Don't use fighter.
Kind of hard to avoid using it when you are as a character that has fighter skillset in the Halloween Mansion. Sure you can just resort to close combat, but the fighter skills are so great in there when you have to fight trolls and orcs for example, seeing as when with a large group you want to get to the room the quickest. Though with the knowledge how it becomes bugged it is easier to avoid in there. Henceforth this thread was kind of useful for me since it made me realize how to avoid my skills getting locked.
Pretty much. Don't know why people continue to use a skillset that's been broken/buggy since it first came out [S]especially in mob situations where other things are a million times better[/S]. And they still think after all these years that it's going to get fixed? Okay.
Sure some other skillsets may be faster and easier to wipe out (an entire group of) monsters. However, not everyone plays to kill the most efficient and quickest ways. Some people play in ways that may take longer to kill but that they find more enjoyable. Some people like to actually have some battle instead of one shotting everything with an AoE as well. Some people enjoy using fighter a whole lot and simply will continue to use it for that reason, despite the fact it has this issue.
