Try to stay under 50% equip load for longer rolls and better stamina regeneration, and try to get your ADP to around 90, then shoot for 100 if you really like the snappiness and i-frames it gives you. The game feels a lot better at 50% with around 100 agility.
It's unfortunate that you have to level up a stat to make the game feel closer to the previous ones, but that's the case so roll with it.
I get it!
I agree, but at the same time it's interesting seeing your character actually improve in those respects as you level up. You wind up feeling a lot more powerful just because you're more agile. Also, having low agility makes the first areas of the game kinda hard compared to DS1 imo. I like how tough the beginning is, and the lack of being able to spam forward roll through everything definitely contributes to that.
