For what it's worth, since going Griffin spec and using casting as my primary DPS I haven't had one combat crash in several days. I've made more progress in that time than I had done up to then. I was planning on being a "warrior mage" style character before anyway, but the combat crashes with the swords as primary solidified my decision. I still use the swords, just not nearly as much, and very occasionally I'll get a micro-second freeze during one or two of the sword animations, but I haven't had a full combat crash since Sunday night. Weird.
The game is very playable for me right now. I'm not forgiving it, and I still want a fix very much because I'd like to feel like I have more options. However, from what some of my gaming friends have experienced with other cards with their bugs and completely random crashes, I'm pretty happy right now. I still do a quicksave before entering fights just in case, but I'd take this over random crashing out of combat for no reason and losing 20 mins of progress for nothing.
