This 100% for me, past three expansion and very closly following thier for thier beta have beliveing 6 months just is really going to be a tight squeeze for giving the game the time it deserves based on previous cycles of changes to a spec to next changes (not just % aura tuning) and that was with only 1/4 of the talents avail and 2 less specs, granted a good portion of talents are just abilities in game already/ are part of a default spec and all your getting is illusion of choice.
BUT now the new interaction between them and what can choose to have together and not lot more is going to be a much higher combination and probably deserves more iterations than before
Granted i havnt followed thier hiring and firing to say they have a bigger developemnt team or not just going to assume equal resoucres so probably should have a bit more time as we dont even have an alpha much less a full 36 specs talent trees to look at or a place to leave dedicated feedback yet to
even ion said on dragonflight release they wanted to get the talents system in the hands of players asap cause thier feedback is vaulable, so with only 6 months and thier past precedence im starting to regard that statement of ions as false and either they dont care about player feedback ( also a concern cause of past precednce) orthey are imo rushing things
also… disclaimer i have already bought the preoder 
i know /shrug
