Little Things Every RPG Should Have @ Destructoid

It's very JRPG focused but Destructoid has a list of The Little Things Every RPG Should Have - such as this one:

Enemies that telegraph when their HP is low:

It's amazing that more RPGs don't do this. In nearly every roleplaying game, your own characters will start to wilt and pant when their HP reaches critical levels. The enemies get to know who is weakest and sometimes will capitalize on that, but why aren't players awarded the same advantage? In the RPGs that do include enemy HP telegraphing, there can be few things more satisfying than finally seeing a hard-fought boss begin to sag and indicate that he's about to give up the ghost. That's when you know to go on an all-out attack, showing no mercy and finishing the job.
