Not sure how it worked back then pre-t2a, but something seems not right at all.

I'm provoking 3/4 different mobs on each other in the west Britain stable.
Bears, a cat and bunnies...
I'm at 30.1 provocation and I have not seen a single gain in 30 minutes or so.

Is some kind of "antimacro" in place? (there should be none)
Is provocation difficult based? (It should't be)
If provocation is working as intended...could I have some hints on how to gain?

I can clarify that the gains are not functioning properly and it is being looked into.

The anti-macro codes have all been disabled. I have to look at it, but I'm pretty sure that provocation is currently difficulty based. You are correct that this shouldn't be the case and this will be addressed.
