Posted in general discussion too, but this is a more...professional place.
Objectives. When you completed them, you got a free mist tank for the tutorial objectives. I'm sure they're going to use objectives in the future more, but just in case.....
Once a day. You get an objective to do something, anything. Maybe reach the 8th floor (After going through 1-7 of course) twice, or maybe go to the arena's end twice. After you finish the objectives, you get a mist tank that expires in a decent amount of time. I'm thinking 3 hours is enough to use any mist energy you have at the moment you finish. Either way, make it temporary to prevent people saving them up.
Make this available only to people in tier 1 people or something. This is a suggestion ONLY to keep this inflation crap from scaring off new people. If you do tier 1 runs that have both an arena AND graveyard/treasure room, you would still barely be able to buy 100 more energy if it's at 5k+ crowns. And you expect all newbies to be able to instantly research what the best places to farm are, and do it mindlessly and repeat until you finally build up enough extra to upgrade one item?
Sorry, but screw you. Purchasing energy with real money should be for people wanting to do more, NOT a requirement to begin playing. Who pays for a game they just started? That's just stupid.
Anyway, I don't want argument on my view of your energy. Just opinions on this suggestion.
First of all, it costs money to keep the servers running. On any given day, look at how many servers are up--that's going to cost a pretty penny. Casual players really only need 100 ME a day; they can play a few floors if they have time, or they can choose to craft something on a day they don't have a lot of time. Using your "objectives" system on T1 players doesn't make a lot of sense because they don't need more than 100 CE to run that tier; furthermore, if they know they can get mist tanks from these quests, they will never buy CE with crowns, let alone buy CE with money.
Better equipment requires a lot of grinding--and that costs OOO money because it's expensive server time. You'll notice that the 4 and 5* equipment costs more CE but provides much better protection than lower * equipment. Theoretically, T2 is the cutoff for free, casual players: if you want to be able to play T3 effectively, you will have to spend a lot of time (a little bit every day) getting crowns to buy CE to craft items. OR, you can pay real money to support the game and get better equipment slightly faster (you'll still have to find the materials etc).
Essentially, it's a trade off between time and money. You mentioned something about newbies researching the best places to farm for mats or crowns----if those people are going to be farming, they're eating up valuable server time.
OOO is running a business; I understand that you're frustrated with the current energy model, but I think your suggestions would make this game far too expensive for OOO to sustain. I would hate to see the game fail because the cost of running it was too high.
