As has been pointed out many times in this thread already, there are many benefits and only one real con.I dont see the reason for the stam changes at all. Its just another unfun change with no balance impact. Almost every patch has something that makes the game less fun. Amazon makes a game that falls short of being fun, while SV makes a fun game and then retroactively makes it unfun.
If the goal is to have armor diversity which is not going to happen with linear negatives from weight then they should have buffed stam regen first and then had armor give penalties to return to the old baselines.
I see no benifit to the current system. Im going to call it that they do a soft reven, half way and still partially have the horrible stam penalties. Its going to be like gas prices when they raise the prive by a dollar then lower it down to half a dollar, so people stop being mad because they think the price decreased.
They really just need to revert it fully.
Choosing to hyper focus in on that single con while ignoring the long list of benefits to the new system can be understandable as that's human nature, but taking a step back and looking at the bigger picture is important for these kinds of core changes.
Henrik has also said that they're going to tweak the system likely in the next patch, so we should see some improvement which will likely be a curve so the amount of penalty you get at lower weights is less, as many people have suggested as a possibility since it was introduced.
Overall this new system as a baseline is far better than the old one, they just need to hone in the values to make it the best it can be, as almost no system is ever perfect in its first iteration.
