blizzard is gonna probably make a bunch of changes inevitably. i hope that balancing, new items, new areas/bosses, and new rules in terms of how battlenet works are all part of it, or at least considered. ive posted my own idea but everyone else's also have a lot of merit.
personally, as long as they dont actually change diablo ii to something different and therefore screw it up, i will probably be satisfied. i dont completely trust blizzard cuz i dont like how d3 looks and im not a fan of wc3 or wow, but i wish them the best of luck in this case.
