Yeah, i guess so.

Hope is right.

I have seen this Suggestion many times Before, and the Same answer Is "NO THEN IT WOULD B PAY 2 WIN LELELELEL" every single Time.

I have even made a suggestion for that as well and everybody hated it.

Honestly I think extended slots (more expensive, but last much longer) or a specialized "timed slot" upgrade would both be worthwhile.

A timed slot would be something that would only tick down when your player is online. They would obviously last shorter than a 30 day slot if you're playing much more (say, they're a 24-hour timed slot for 100 energy (trinket), or 24-hour timed slot for 200 energy (weapon)). Thus, if you play more than 24 hours monthly, it'll be better to just spend 50 energy extra to fill that slot.
If you got a monthly slot the timed slot would stop counting down until that time period is over.

Extended slots would be like, 90 day, 180 days, and 365 day slot upgrades. Have them be cheaper if you buy them up front (425ce for a 90 day trinket slot, 825ce for a 180 day trinket slot, 1600ce for a 365 day trinket slot).

Slots are a subscription model. However, in Spiral Knights, you're only given one method of payment. Typical subscription have a month, 3 month, 6 month, and yearly subscription options. Spiral Knights only has the month option, which can be expanded upon.
You can easily make 1600ce in a year's time. However it can be difficult to get your players playing the entirety of a year.

^Cool story bro.

We frankly don't care.

They're basically a 'subscription.

Is that a problem? Personally I would prefer that 000 had a premium membership than rely on box promotions. If part of that membership meant free slot boosters every month in addition to whatever goodies it came with, that would be optimal in my opinion.

Yes, generally, selling cosmetics is preferable to selling power. The problem is that when you sell too much cosmetics and you get to the point where a huge portion of your income comes from people who don't play the game but just merch or try to look pretty, development on actual content starts grinding to a crawl in favor of selling cosmetics.

I think that they could make considerably more by selling permanent slots than they do by selling temporary ones... and I think this because it's hard for many to wrap their head around the idea that they are not eternal.

The logic against permanent slots goes that if you buy slot tokens from now until infinity, Three Rings makes infinite moneys off of you, and receives a supposedly steady income in the process. This however is short sighted, because no one is going to play from now until infinity, and chances are the bulk of players are going to minmax their slots-- not playing heavily for a month becomes the same as not buying slots for a month, for many players at least. Rather than making 12 slots worth of profit, they might make 10, 8, far less depending on the player. On top of that is the fact that players see themselves as being elated for skipping out on weapon slots- you might beat the tortodrone, but I beat the tortodrone without a third weapon slot = I am the spiralest knightlier knight!

Permanent weapon slots would be like tricking the knight into buying 10, 15 even 30 years worth of slots all at once. Who in their right mind would buy 30 years worth of weapon slots all at once? Only people that are willing to show their commitment to the game, get that badge of honor, and feel complete.

Permanent weapon slots would be like tricking the knight into buying 10, 15 even 30 years worth of slots all at once.

Except that if a permanent slot cost 1620000 CR or its CE equivalent most people would just not spend that much.

The difference is that on a per-month basis, the cost of a slot seems cheap, and that's good for 000 to get people convinced to sink CE into it.
