While I don't have a core issue with the argument many like you have which is simply "I don't like the change", your post here is just downright silly. WM doesn't change BRD anywhere close to what your suggesting here. It makes it stationary and gives it a cast time and it is a form you can leave and enter instantly. If WM changed it as much as you suggested you would need to play BRD in Plate, with a spear, in melee range and have to deal with positionals.
Secondly, DRG did have pretty major mechanical changes and in some ways they are as big as WM. The Blood of the Dragon mechanic gave them a bunch of MNK like mechanics, including the need to sustain a buff using complete combos and positionals.
BRDs haven't had it harder when it comes to mastering or dealing with the change, particularly in how it impacts fight mechanics.
The only valid issue at this point with WM is really that some people don't like it. That's a perfectly valid issue. I don't think its enough people to trigger a change though. I've been seeing people in game who have actually started to enjoy it.
