If you're going to play DS2, you need to read this, don't care if it's a spoiler free new run or not:

Takeaway: Get your Adaptability up enough to raise your Agility to 100. Doing so will give you faster item usage and if you get it to 105, you have exactly the same iframes as the fast roll in DS1. 99 is really close, 100 gives you the quicker item usage.
Code:
Agility iFrames
85 5
86 8
88 9
92 10
96 11
99 12
105 13
111 14
114 15
116 16
Another thing, anything up to 70% weight burden is totally fine - it'll lower the
distance you can roll as it increases (and very slightly increase falling damage), but it does
not affect your iframes, you still have the same invincibility period.
TLDR:
Raise your agility to improve dodge roll iframes and item use speed, do it now.
