I have found that Spiral Knights is kind of a punishing game.
The game is still fun, and I will still play it and enjoy, but if this issue is solved, the game would be even more enjoyable.
The difficulty system is a factor in this problem, though it's very, very small.
Elite mode cranks up the monster health, but all this does is make the easy monsters still easy, and the difficulty spikes more.. spiky. This means that the difficult monsters are more frustrating. But, we have to deal with elite mode in order to get more crowns and rarities.
The main factor of the problem that has been with this game longer is Difficulty Spikes.
There are some monsters that are easy(slimes and beasts), but some that are tough(fiends and undead). The monsters need to be more consistent in difficulty to lessen this issue. There are also cheap attacks that come with this. Cheap attacks like sudden-thwacker-spin-attack-MANIA, stupid-mender-runes-that-heal-to-much-and-aren't-balanced, stupid-mender-revives-that-slow-down-battle-progress, and minimonsters-that-hurt-on-contact,-unlike-the-other-monsters.
Now, I'm experienced enough to ignore some of these problems longer, but if you want to give a more satisfying experience for more players, this is something to look into.

Practice makes perfect! No game is all that punishing, getting really good just takes time
