Disagree entirely. Limit your healing items and the game will get a lot harder. You have to be so much more careful. Its why you see so many people kindle bonfires. It obvious helps them as it effectively cancels the mistakes they have been making prior to the boss.
Well then you missed my point. Grass, as a collection of healing items ( not just full heal) was ridicoulously easy. Dozens of enemies dropped it, in large quantities, regularly and can be bought cheaply as well (unlimited stock too). Humanity is nothing like that. Gems are nothing like humanity.
I will probably limit myself to just gems and use flask when an invader comes.
I see your point that limiting healing items makes people play more cautiously, and it sounds like (from people watching the early stream) that healing items are more limited than they were in DkS at the start. So hey, whatever.
If we're talking from a purely PvE perspective... who cares how other people play the game? Let them get their enjoyment from it. It doesn't impact you in the slightest.
PvP-wise, if you let someone heal to full without them popping a full-heal item. Well, that's your fault. You're bad at PvPing in a Souls game if someone can just be a turtle against you.
