What I'm trying to get across is that energy is needed too often in the game. What I am suggesting is that you should either lower energy prices or remove it from some of the places you have implemented it.
I tried not to make this so personal but what can you do? I'm sure I'm not the only one either.
Now I'm a player who plays for free. I will never use my money for this game, period. As advertised this game can be played completely free. No doubt about it, however if we choose we may indeed spend real money to "better our experience" with the game. Nearly all games are similiar in this aspect. This is the only game that I have seen that punches you in the face with BUY BUY BUY.
Let me give you an example of how my free games goes on spiral knights.
I login and I got 100 mist energy and a couple thousand crowns. I go dungeon slaying and spend all my energy making a couple thousand more crowns. I log off. Maybe a day or two goes by and I login again. I need to craft some three star items today (also now that we have missions its mandatory to keep completing missions that you need better equipment, but you already know this). Ok lets see, it cost 200 energy and X amount of crowns and I have 100 mist energy so I need 100 more before I can craft, goodbye crowns. I spend nearly all my crowns and I can make my item, so for today thats it...bummer I wanted to play after I crafted my item, oh and I still need to make the gun, the sword, the shield, and the helmet.
Now then, over time I will keep continuing this process. Assuming it takes me one day to make enough crowns to buy CE, when I craft these items thats a total of 5 days I don't get to play because I had to craft something. (this is just an example and I'm not inerested in hearing how you "pros" make more and do this faster)
Continueing from "buy buy buy" and how often energy is needed, it's litteraly smacking anyone including me who plays completely free. If I want to play, I need energy, if I die, I need energy to revive (which increases the more a player dies), If i wan't to do a challenge, I need energy, If I want to unlock some mechs (which themselves cost 5 energy), I need energy, if I wan't to unlock some treasure I need energy, if I wan't to craft I need energy, and then you got all those little fees in the auction house.
This is some serious milking your doing. For those who use money it's not that bad but for players like me who play free it takes quite the toll.
I started playing spiral knights when it first came out and I quit because of this. I only came back to see if its gotten better and it hasn't. Now critics will most likely say don't play if you don't like it but I love this game, its so fun but your trying so hard to get me to spend money that it pushes me away, your pushing a fan away.
What I want to pinpoint on now is my suggestions in more detail. (also I don't use/rarely use my CE because it is too valuable, I use it strickly for crafting, keep that in mind for anyone who doesn't spend money, and to counter a possible arguement if I completed my armor and weapons then yes I would use CE for dungeon diving)
earlier I said what the energy is needed for, I don't have a problem with everything.
I play solo a lot and I die occasionally and it cost energy to revive, that is understandable but when it starts costing the price of an elevator (10) and still keeps increasing 20, etc. It can really shorten that 100 mist energy. Make a set value and don't raise it. (like kicking someone when they are on the ground)
For the challenges a player is already risking taking damage and getting killed just by entering and your going to charge me 3 energy?
Just make it free.
Is not the point of treasure (crowns, heat, potions, health, etc) to fight for it? But no, there it is in a square chamber, your's for a price. Again you charge us 3 energy.
I reccomend just making it harder to get ie. traps and more monsters.
Again for the mechs its the same thing, they already cost 5 energy and your charging us just to unlock them. Use more traps or monsters or have less mechs in the room, otherwise don't make a gate for 3 energy or lower the mechs price. (Why would I waste 8+ energy (depending on how many a person activates) for something that can damage me and doesn't last until I'm done playing?)
My biggest issue was the crafting which was why I used that example. I need that energy to go to dungeons and make crowns to buy CE but it gets wasted to make a piece of armor. Lower the amount of energy or come up with an alternative, maybe giving more purpose to "heat" making it useable in crafting? hmmm ideas? It powers up our weapons, wouldn't it make more sense to use it as crafting also?
ex for using heat. before exploring the clockworks you have the option to choose how your "heat" is used like half for weapons and armor and half for crafting currency or you make it 1/4 currency and the rest for weapons and armor.
Overall you keep poking at players to buy with money, your nickel and diming us. You are doing it to harshly. I've never seen it so forced like this.
You don't change it because not enough players stand up and say it or because you have so many players it doesn't matter if a couple thousand don't agree. Yes, I'm calling you out and making a rash assumption but am I completely wrong?
Yes if you do these changes the economy will change in the game. Those who pay with actual money will be getting a bigger advantage. However the free players will be able to better enjoy the game, it will bring more players overall and maybe some willing to spend some cash and the creaters will still be making millions or billions, however much you guys make. So what if you lose money out of it, your still making so much and it shows you care more about the players.
If you really are annoyed by this, I seriously recommend acquiring an elevator pass. 30 days without any elevator costs.
