Tried a Stone/Stone Scrapper, got to level 12 through street sweeping in Atlas and running Hollows arcs. Seems to be a good armor set so far on the AT, but Earth's Embrace feels like the heal is too weak. I think it should be increased at least some.
On another note: I have a Stone/SS tank that really appreciates the changes, other than Earth's Embrace having too weak of a heal now.
As for the minimal setting for the powers: I love them! They seem really well done, I particularly appreciate the Rooted minimal. I'm not sure how difficult it is, or if it's being worked on, but I would definitely appreciate a non-model swap option for Granite Armor.
For Brutes: is it really appropriate for their version of Granite Armor to have the same magnitude of penalties, despite the reduced effectiveness compared to the Tanker version?
For Rooted and Granite: I feel like it would be a good change to simply scrap the movement penalty from Rooted altogether. Getting rid of it entirely would be welcome for emergency switches.
Overall, I think the revamp and proliferation are very well done.
(I apologize if I poorly structured this post, or put too many thoughts at once into it.)
