Of course you can always use a potion now and then, but it's a little bit too frustrating if you need to SPAM many potions, that kind of "strategy" I don't like ...
True, I also don't like the idea of guzzling potions like BEAR

If you regularly need to drink lots of potions just to survive in tough situations then chances are your build is far from a good one. A stealthy character build with low health, one which focuses on delivering fast but heavy damage, might be an exception though. But DKS isn't ideal for those type of character designs.
About strategy planning, what can I say? That's one of the key aspects which makes RPG what it is and I hope they keep it that way.
