I think what is being got at is that how is the reduction in the number of DPS spells make things more interesting for a job that already only had a handful of them? A few extra spells helped breakup the monotony a little more.

Comparing to MCH is not a fair comparison, if 55% of the time MCH was hitting Drill in group content, then maybe it will be fairer and I bet you MCH would be complaining how boring their job has gotten. Or better yet 90% of the time you are doing solo content. Because this is not only how it feels to DPS on a healer (and not just WHM).
