New mastery Expose Weakness should be swapped with Assassin
As a low level play who loves playing support (just got out of bronze, Woo) I was thrilled that they added a new master to help a supportive player, but its location is in a place where full support builds (In the mastery tree) cant really reach, I personaly go 9 in the Cunning tree and 21 in the Resolve tree (there wasn't any reason to go down the Ferocity due to it being solely dps based , that was before Expose Weakness~). Expose Weakness being in the ferocity tree seams out of place and would be more fitting in the Cunning tree (it makes sense for a cunning person to expose a weakness...), and for Expose Weakness to fit into the cunning tree, assassin should be moved over to the ferocity tree. (I don't play too many assassins but I would expect they would go full dps and spec into, 21 in cunning and 9 in ferocity or the other way round), even though this would make the tier 2 masters in the ferocity tree seam plain (A 3% bones in a given situation or a 2/3% bonus with a trade--off).
Add a comment on your opinion if you think this should be changed too, ty for reading

lately and I actually like this in the ferocity tree. I'm super aggressive for a support and I am considering setting
up as 9/21 now. Currently I just get Expose Weakness in ferocity in dump the rest into the other 2 trees so like 6-21-3 or something like that. I dunno. this might work for me as a super aggressive support, especially with some adc's that struggle early on. I know champs like ashe and early game vayne or kog might like this on a support rather than some of the other options I see available.
