I wouldn't think so Thorn, If anything I would think you would be ahead for the most part. We started the Re-Roll on a Wednesday to miss the patch day (If there is one). I also work 40 hours per week, and I have 2 kids. And when we set the leveling caps, they will have some room for people that work also, now I'm not giving people 3 weeks to hit level 60 or anything like that.
I might be getting to deep into your question at this point, haha. Basically no, I don't think you would be behind working throughout the weekend, especially if you have the rest of the days off. I work Wednesday, Thursday and Friday this week, so I kinda feel like I'll be behind! haha
