Hello. I've been playing Spiral Knights for about two months now, and every time I come up to a Hall of Heroes mission, I get stuck on the rank for weeks or more at a time. I've heard multiple complaints from some different people (Not saying any names) that leveling up is a little too hard for them.
Fire Crystals - Fire Crystals ca be pretty hard to get if you are higher in ranks. Purchasing them with energy can be costly and some people may not be able to afford them, in real life.
Orbs of Alchemy - Same applies here. Eternal Orbs are very hard to find, and can cost up to $10 to buy enough with energy. It is possible to get them from mission rewards, but you don't get enough.
Recipes - In order to level up, you need stronger gear. Recipes can get a little costly, though. At first, you need 4,000 crowns, then you need 16,000 crowns, then you need 40,000 crowns and then you come up to 100,000 crowns, just to level up.
I know most people won't have a problem, and Vanguards manage to end up with hundreds of thousands of crowns by doing missions. But in lower ranks, where you need the crowns, each mission only gives you 2,000 crowns per run. I haven't thought about what the prices of this can be decreased to, I was just thinking about how it costs so much now with the new update (According to more experienced players). In my opinion, it just takes too long to get sufficient crowns by doing missions. I hope you get to read what I've posted, and give some comments/complaints about it. My idea still needs improving, since this is the first time I have posted on the forums.
Erm, that's SK dude. At least you don't have to deal with waiting for your mist to regen before you can keep playing anymore... of course now you need to use the Fire Crystals....
Point being, the game is kinda about grinding. Get used to it.
