So I was pretty tempted to open this by shouting something like no you fucking morons grinding currency is more exciting than rolling the dice 50 million fucking times "over the long term" but let's save that rant for another time. Theirs a benefit for the developers end to rng in character progression, it extends the life of content and potentially masks long and unpleasant grinds. Having said that I think that's incredible poor motivation to offer players. The greater motivation is the reward you can see. They seem to think that deterministic reward schemes are boring in the long term but isn't that basically what lvling is? And isn't that was people come back for every expansion?Grinding lots of currency and then visiting a vendor to purchase a piece of gear wasn't very exciting over the long term.
