Honestly, it's disappointing to see how much the Mission UI ruined Spiral Knights. [/personal opinion]
I mean something that crossed my mind, how many people have actually tried the new compound levels? If more than once out of the entirety of Spiral Knights?
I see many "Arcade" revival topics and I feel that it really should be revived but the only way to revive it really is one simple way: Removing the mission UI.
Missions: Get rid of them
Missions turned Spiral Knights into a "Money > Fun" instead of "Money < Fun". I remember going into Arcade with random people even if they were noobs and having fun with just going through random set of levels each time. The Arcade features a random string of levels that give the player a sense of mystery surrounding the clockworks. Allowing them to play through semi-random levels without knowing what was ahead. (Unless you're a true pro)
Missions remove this sense of being able to choose your own path with a straight forward Story that really offers nothing new to the game aside from the overly-used insta-jumps to Bosses. And, no, "locking" a specific mission after completion still doesn't fix the problem because it can easily be exploited.
However, instead of removing all of the missions...
Mission Specific Additions: Adding them to Arcade:
How about we add them into the Arcade instead?
There are a few perks to the Mission UI which are the few unique-lore missions such as The Silent Legion and other missions. What would happen if we added these into a "Scenario Level" akin to the Scenario Rooms? The game had a sense of mystery wrapped around it. You never know what you'd encounter in the clockworks. Scenario Levels would add to this. With a random chance of accessing a unique-level keeps the experience high, showing the player that "There's a lot more going on than what it seems". Imagine going down into the Clockworks, only to find yourself stranded in a completely new-unknown level. Seeing rooms like these honestly, sound interesting and some of them are really worthy of it.
Prestige and Expansions: Keep them
Rather than removing these, they should stay in their own tab much like what missions do now. Giving players who currently have prestige (and also Danger Missions) the enjoyment of a quick jump if they feel like. Along with any Expansion Packs kept currently.
Content that feels new but isn't gobbled down: Compounds and future installments
Much like the first question I asked in this topic, how many people have actually run this? From what I've seen, not that many out of the entire player-base. People complain about no new content yet the content was added... and no one has actually attempted to try it out. All because Money is more important than Fun OOO could easily add more levels akin to Compounds and people wouldn't eat right through them. They'd slowly take their time enjoying their meal or even snack every so often instead of gulping it down and saying "Done". With Missions going on, people don't realize that there's a lot more in the Arcade than what the Mission UI could ever achieve.
There's not much really to add here aside from what I've said. All of it is opinion based and may or may not reflect upon other views of players. Much like I said before, I do not expect this to get great views and I understand that constructive criticism is important. I hope some people agree with me and the ones that don't express why or what could be changed. Thanks.
I like this idea, “Mission Specific Additions: Adding them to Arcade" but I rather not see a mission I have already completed. I would rather see a new mission that is specifically design for the clockworks randomness.
You’re other ideas, I don’t agree with. The developers (probably) took a lot of time making those mission scenarios to give a storyline t the game. Removing them is really throwing away good work. They should instead do what is suggested in this post ( http://forums.spiralknights.com/en/node/72817 )
