Many players have had to deal with the way combat is and how sync and stim spamming have made is so that explosives and having more stim packs then the other person is the best way to win. Hard mode would change this as it would make awareness and accuracy more important then weather of not you are going to have more stim packs then the other person but the effects are more far reaching then this. Limb damage requires sleep or a doctors bag to fix, ammo is heavy so no more 100000 MF rounds farmed at repcon HQ and missiles and other explosives even more so when fights are tense quick and a real risk even when your running away the game will be harder yes but also more skill based. If you note that the needs system would have next to no effect on players with the ease of getting food in the first place on top of the fact that any time you D/C it would reset then it has little against it in that regard the primary factor is that it changes the way healing works such that fights can be over quickly like they would be like against any other enemy in the game healing still has a place and a role in the way we fight but it is not the only factor when we note that players who are not synced can't damage each other any way (done a fair amount of combat and have watched people take rockets point blank and take no damage) and the fact that if you were going to get one shot by a rocket then that would of happened anyway it means healing this way would be an excellent change add on that you won't be able to carry that many rockets anyway and it has an indirect nerf on that aspect too. If you follow that up by making guns save again and making barter the skill that does not (when you consider you can farm caps in so many ways and if your lazy can just go to prim and farm 3 frag mines for 8k the skill is kind of worthless ironic that aint it) and you bring them back as well which would change the meta on another level from just the Q-35, YCS, and a explosive weapon of your choice to include the large variety of gun's that are present in game a change many would welcome.
