The following tags are used as main character tags:

Now, given that fate/apocrypha, fate/extra, fate/prototype, and the fate/grand_order Epic of Remnant servants (who should have their true names hidden) all show their true names, should the past tags do so too?

I personally think that true names should be added as aliases to the class name for the lesser-known servants, or for those that don't have alts on F/GO, since that's what pretty much throws a wrench in the entire thing. Although giving only certain servants their true name as main tag also adds inconsistency.

Some of these tags, not having true names aliased to them, also makes tagging harder. in my experience, i spent half an hour finding out where all Hassans of post #3676840 come from, since the tagging is pretty inconsistent.

I personally think it's still worth keeping certain names hidden, like archer.
