This game doesn't need any save or help or anything.
- it has been sold for +12mil of copies, it has been played,
- the RMAH gave them alot of money (probably),
- patches are making community to come back for a while and play,
- about 12k heroes have 100 paragon level, that's alot. Think thank only a part of playerbase has done it.
They are calmly making and expansion, witch will 99% sure sell like 8mil copies, ppl will come back, RMAH again, maybe some new systems will make ppl stay longer, more money for blizz, that's all.
There is no pressure. If you want D2, play D2
Or play PoE and get bored.
You know what the group of forumers are saying "this game needs repair, needs save"? Because you just want a product to spend your life with. You want a product for years of +4h/day gameplay or even more. Thats all. D3 played casually, from time to time, for fun, after a hard work day, will last for at least a year or two. The only problem is lack of competition and current market is based on it, ppl want to compete with each other, whatever it is moba/pvp or pve showoff/race. D3 has no common competition.
Sometimes I think that many ppl here are just addicted.
