Yes, if Finnair really wants to make plus partners into a good business these things has to be addressed. I too never use the partner system, not even for cake-combs.
Get a decent backbone for partners to do online points settlement, clean up the partner pages and make sure info is rock solid, demand partners also engage in this. I believe SK is operating a fairly successful partner program so it can be done. But for Finnair it looks like an operation the cat dragged in.
