I´d welcome it. As Ion stated the leveling process in terms of numbers felt just irrelevant the last two expansions.
Also I don´t like these huge numbers which also "could" alienate newer players even if they have a levelboost ready.
Reduce the levels but make them more relevant again. We hadn´t new talents since WoD, while in Legion it was fine due to the artifact weapons in Bfa it lacks something because the azerite traits feel more like a T-Set bonus than talents or whatsoever.
I would love to see the old talent trees return in a more worked out state
