If you won't be using the trinket for it's value then don't buy it. If you want it then buy it. Your problem. Don't start stealing out of the pockets of a f2p game, they need to make money somewhere.

I believe we've already discussed this in depth (and only like a week ago?), but I'll repeat my argument here as well for the sake of it.

@"This will lose the developers money that they need though!"

No one plays Spiral Knights forever. Everyone thinks that they do, and therefore plays like they do, but they don't. If the market audience of such a slot pass had to overpay on average, then it could actually benefit the developers financially. Since the cost of these slots is actually pretty cheap, forcing players to pay for ten years is only like 30,000 energy, which is a pretty safe bet if you ask me- Spiral Knights hasn't even been here for 10 years. No one has ever played for 10 years. But people would buy it, because they want their account to be more or less "complete", and this would be one huge step that requires energy to overcome.

This simple fact covers the harshest condition- that only players buying slots constantly would partake in this. There are a LOT of players that don't buy weapon slots at all and even more that cap out at 3 slots instead of 4, lack trinkets. If they could be made to stupidly purchase a 10 year weapon upgrade that lasts forever, it would be a huge benefit to the developers. Marginally more than them buying weapon slots for two years and then quitting.

Instead of making them permanent, how about they expire when your ONLINE for the span of 30 days, then the timer pauses when you're offline.

Well it's true that it doesn't make sense for them to expire while offline. But definitely nothing permanent.
