It is fine, and the hunt ones is very much valid from day 1 to to FFXIV 2025 and so is most PvP, if you are engaged in either thing you would know why and it would also show which parts of the game you like where as others will never ever get close to any of them.

As for slaying A Rank Hunt marks, then all levels of it count, be it ARR or DT.

Some more stuff to spend the extra tokens on would be nice.
