Thinking that resource management in an MMO is outdated and unfun is purely subjective. Given the length of this thread there are obviously outspoken people against proper resource management, and there are plenty of other games that they can play instead.
If IMC decides to tone down SP consumption it will just make the game boring to the other side of the aisle that appreciates resource management in their MMOs.
The only thing I agree with you on is the Stat system, giving up our ability to customize our stats was a step backwards and I hope they flip it back.
