Will there be more burnout due to so many BIS items coming from Ulduar 10

Back in the day there were a lot less BIS items from the 10 person version but due to the ilevel buff this is a bit different. As a result you're seeing many people raiding multiple versions every week on their mains and alts. The sheer amount of time can certainly lead to burnout.I noticed in my guild for example people running 3-4 raids just in a day. It doesn't help that for some classes it's not just the bis but also 2nd bis which is also from the 10 person version.
