There is a reason to do PF if you want the mount and/or speed rewards for doing it. Or if you just like to do achievements. There are benefits to doing the meta achievements for PF if you want the “extra” rewards.
Additonally, on every alt you have to purchase flight so you can fly in every zone prior to Draenor anyway. After the change, you still have to purchase flight for all other zones anyway and Draenor/Legion zones will be included with the purchase so you don’t have to do PF. It’s not like they are adding cost to fly in those zones for people who have already obtained PF.
They are actually lowering the overall cost by removing the 280 speed skill and only having to buy 4 of them on alts (which you already have to do anyway if you want to fly anywhere outside of Draenor / Broken Shore / BfA areas).
I just don’t see the big deal.
I do PF in current content because I want to fly, I do all the necessary things with or without reward (even beyond up to exalted with all reps because I like to see those shiny green bars), enjoy grinding achievements, like the challenge of finding all the “treasures” when there is actually a little difficulty in doing so, and more. The point of doing it, for me, is so I don’t have to wait 2 expansions from now to fly in areas I am going to spend all of the current expansion playing in.
Also, what’s the difference between today and after the change? You were already doing PF, waiting 7-10 months to fly after doing all the content repeatedly to actually be able to fly.
They are not unlocking flight in BfA, only in the super old expansion content where keeping it makes little sense anymore, especially after the change to how questing, levels, and zones will work.
We’ve never been able to fly only from doing questing in the current content. There have always been exploration and rep requirements also, and there was once treasure hunting requirements. This is exactly how Shadowlands PF will work.
Players played this game just fine before PF was a thing. They will play when PF is no longer a thing (and the next flight unlock mechanism is put in place, or whatever happens). I am seriously confused by your post… I just don’t understand your argument or complaint. What you’re saying makes little sense to me.
