Looking at our list once more, we do agree it might be a bit lengthy. We like your list, Shienvien.
Some GMs might want a way to indicate how many slots are left if they have restrictions on such, but we are open for other ideas on how to do that than the lengthy one we had.

we're honestly not sure how many RPs outside arena and free will use the "jump in"-tag.

We do disagree a bit with removing the NRP section, but only so long as the free/casual/advanced tags can be applied within it. Same goes for tabletop.
