I was thinking about it, and although the news says more hearts will be added in the future, and I don't think it is a great idea. PKing in this game is slow and tedious, and it can take ages to kill somebody because of connection and other things. On many of the PC servers, more hearts is countered with ways to kill people faster and different damage amounts per weapon, but this is not the case here. EVERYTHING does 0.5 damage here, and having more than the default 3 hearts would make PK even more of a chore. And NO, I do not want more hats and "filler" quest rewards, but maybe something tangible with a purpose, (like the bug net) like the power glove would be a better reward all things considered. Not trying to be a stick in the mud, but the way iclassic is currently would not work well with more hearts.
