Ok, so I’m sure you all know this, but the rolling thing in DS3 is tweaked a bit. Same formulae for fat roll, mid roll, fast roll, however, both mid and fast give you the same IFrames (13), fast just moves you further.
I’m fast roll for life, but in this game I’ve been using the mid so I can actually wear armor for once, and it works just fine.
edit for wiki inclusion:
Weight Ratio %
29.9% or less Fastest state: very fast rolls that go the farthest, with 13 iframes. Fast backsteps.
30.0% – 69.9% Regular state: medium rolls with 13 iframes. Fast backsteps.
70.0% – 99.9% Slow state (“fat rolling”): slow and short rolls with 12 iframes. Slow backsteps. Stamina regenerates about 20% slower.*
100.0% or higher Overburdened: cannot roll, backstep or run. The walking animation changes.
