Honestly, move on. There are mechanics at play in DkS - and I understand similar ones in LotF - that will eat stamina according to your shield stability and I think in DkS1 poise was added. If all stamina is lost your guard break and you are pretty much dead in the water. And once you get into deeper playthroughs it gets more pronounced.
Then again my only experience with shields and poise is the tree boss

(and a steel+10 I used in Demon's to run through 4-2 for farming. It lost effectiveness completely a few playthroughs in).
However, what DkS1 got seriously wrong for Dex Chars was a) the Uchi's sucked. and b) no dual wielding.
The games you continue to cite baffle me. I played a bit of Dragon's Dogma and some Amalur. Both bore me to tears. DD "nailed" combat? You and Souls fans are looking for entirely different things in their games. Just accept that.
Now about Bayo2. Should I get a WiiU or not? I would just focus on the flashback challenges in NG3:RE, but I can't stomach the levels to get to them
