Old beast Tribes

So, after doing old beast tribes I never got around to, this came into my mind, you know after enduring the moogles and attempting to endure the 50 rep per quest. Which is annoying since you have to blow through at least one daily turn in to get that added rep you need to rank up. Anyways, I know we can only do 12 a day which is fine. But for older expacs why can't we just use all 12 on them since they are old content and to have to time gated for so long doesn't make sense to me. I doubt people really want to do the older ones for like 2 months(?) to finish them at this point. Mind you I don't know the time frame to finish one at 50 rep a quest turn in and don't want to do the math at this time. I am not saying to give us more beast tribe allowances just allow us to do all 12 in one day one a single older beast tribe if we choose to. It would be a greatly loved thing after having to do them. Thoughts?

Eventually you can. ARR beast tribes work differently. You start with one quest giver, then as you rank up more unlock.
So by the end, you can spend all 12 allowances on a single tribe.
