With old system, ppl kept whining, that to give out some big uber loots mindark keeps average loot down. Now with average loot up ppl whine that big uberhofs are too rare, because average loot has improved...
I think we are customers who are impossible to satisfy.
No, the real problem is that the whole system is fundamentally flawed as we're talking about an entire economy that's based on an unsustainable formula.
The mining system in particular - I don't think their motivation for the change had anything to do about people whining I think it was more motivated by the fact that the old system couldn't support further growth of the universe. I mean think about it, the more surface area that there is in the game where you can mine the further out resources need to be spaced to give a decent coverage of available claims. And I don't want to hear any of this crap about the resources not being in the ground and it all being random based on the avatar dropping the bomb because if that were true you would be able to get just as good of a return by standing in one place continually dropping bombs.
Anyways, add in the fact that they now have 2 locations that have larger claims (foma + hell) and the fact there are a wide variety of amps available to force larger claim sizes, plus the fact that unlike in the hunting system there are no "partial loots" for mining (as opposed to hunting where you can loot 0 TT items). If you hit a claim it's got full TT value with the RARE exception to finding some SOTO's and you've got a system that's dependent on the steady flow of peds into the loot pool which is primarily funded by 2 sources. 1 being NRF bomb drops the other being amp decay (I'm pretty sure MA stated officially that amp decay goes to the loot pool only and not their pocket).
They already tried to improve the flow of peds in by getting rid of blast marks a long time ago which meant more people would be mining the same area as someone else and now with this new system it's in effect reducing the advantage of using amps as the opportunity for really super huge claims is much less likely than it was before...
The main thing you have to consider is MA's motivation for everything they do which IS NOT to appease the players - their main focus is to stay profitable. And based on their current income strategy the only way they can make more money is if more people stay in game and have more decay on their stuff. Meaning, it's better for business if players are able to go out mining and have closer to a 90% - 100% return as they'll more than likely come back, repair (pay MA) then go back out to do it again over and over until all their money has gone to repair bills (MA's pocket). However there's a fine line in doing this because if the returns are never more than 90% - 100% people may just get bored and stop mining all together.
Bottom Line...
I imagine right now they're testing things to see what the user retention rate /profit is when the returns are closer to an average of 90%-100% and the dangling carrot of a potential ATH is no longer there, or at least not as prevalent.
Which scenario means more money in MA's pocket?
1. Lower average returns but a lot more huge HoF's (specifically Hof's under 4000 peds to maximize excavator decay) in the hopes that more people will keep pumping in money for mining because a huge HoF seems SO possible at any minute. Possible downside might be that new players with low bankroll might get screwed right off the bat and never play again (a huge negative especially now that MA is pumping money into advertising to get these new players in the first place).
2. More breakeven returns with large HoF's being less likely. With the assumption being that this will keep new players interested enough to keep playing until they get hooked and existing players will keep playing because they're getting more break evens even with large HoF's being less likely. SO that in the long run there will be more of a chance for MA to widdle down a players bankrole in finder + excavator decay which goes right into their pocket as profit.
Once MA has the answer the system will be adjusted accordingly. Personally I prefer the old system over their current system but I feel that neither system was flawless.
