On the other hand,
all software releases from Symantec need patches... I'd say go with MP1. If worried, wait another week and keep an eye on this forum.
After checking the fix list in the release notes I found at least 7-8 issues we have in our environment. If these issues actually are fixed now, and hopefully for good, this release might be the first good one in the 11.0 series.
We'll start planning a 10k deployment now and run a pilot to see if all goes well...
