My only complaint is where you unlock WM in the skilltree. Mchs as well to a lesser extent.New players that choose archer will be playing with instant shots and free movement up untill lvl 52 then suddenly chahge to casting.
No other jobs change as drastically in there main branch (melee still melee from 1 - 60, healers still heal with casts etc)
and that will confuse and even put off the newer players, especially if they dont know WM is even a thing.
Luckily you can switch jobs whenever you want
