Yes, sporadic use is a major issue on top of the fact that this is not SaaS and nothing lives in the cloud (which of course I don't want of a document creation tool anyway).

I am all for layers of features that cost money to unlock, but never ever ever on a subscription basis. It's like every developer out there heard that SaaS is where the money is at and decided that applied to their project out of dogma rather than a well reasoned business case.
