Just saying, but fanservice has a definition and almost everything in this game is some form of fanservice. Viera and Hrothgar are absolutely fanservice, as per definition. That is fact, and there's nothing wrong with it.
Yes, it is probably a matter of resources and pleasing the most amount of people, but I think it is also absurd to say "you're not allowed to be mad" or "don't bring your agenda here" to people who constantly lose out to strong/burly men and cute/sexy women stereotypes and want to be included or are annoyed that this is what SE went with.
The market is oversaturated with online games where the men are either strong/hyper-masculine/monstrous types and the women are cute/kemonomimi/sexy types, so you'll excuse us for wanting something different for once.
