It certainly depends on what you are trying to accomplish. That "performance expert" (who lives near me now) never said NO IMP=1; but rather reserve it for mission-critical work, short- important transactions, and emergency work. If you put a lot of work into IMP=1, there is no UP when you need to get something done in a hurry. If you look at at the IMP levels as a bell curve (or a slightly skewed to the right one), WLM seems to do well with a little bit of work in IMP=1, more in IMP=2, more to much more in IMP=3, more in IMP=4, and a little in IMP=5. Remember that WLM starts at IMP=1 to be sure that work gets done, and moves down to IMP=5 and DISC. And we're not going to start a war on whether there should or should not be DISC work. It is desirable that IMP=1 and 2 have a good PI, and the rest maybe, not so much. Also remember, the WLM robs Peter to pay Paul, so you really want work in all of the IMP levels. Of course, this is all IMHO, and your mileage will vary. This technique has worked in all the many sites that I've helped with WLM.
