A mistake by Phreak for the Swain R max HP:
For the swain passive to be even/higher during the R, just for the 125-275 bonus HP from the R, you need 18/29/40 souls. +7 more per soul than before (old 5, now 12).
But the old R also doubled the HP from the passive during the duration. So during the R you gained 10 HP per soul before and now you get 12. that means +2 only.
So the actual numbers for even/more max HP during the R is 63/100/138 souls. And I dont think anyone will normally have that many souls at lvl 6/11/16, especially because you cant get them from allied CCs anymore (less souls later on).
The P does give more total HP outside of the R. But it is also less than expected later on in the game as you do get less stacks.
Edit: Also another mistake: Double stopwatch is still possible, it just has 1 more restriction compared to before. You have to upgrade to GA/Zhonyas after buying the 2nd stopwatch and before using ...
