I find it deceivingly uncongruous how you push so eloquently for the untapped potential of Spiral Knights, including the Silver Keys (for cosmetics) yet stop dead on track at the price for Shadow Keys (for integral gameplay content).

I recommend you allow people to find your thread on Suggestions, and you leave it at that. What St John said already is right, this has all already been discussed in Suggestions.

P.S. Ninja-Kong I hope you don't bombard people with your opinions like you did to me in-game today. You are screaming 'fire!' in a burned down theater.

spyro knight is a bad zeldo ripoff 0/10 forge has no progress value whatsoever and all events are bad since they involve grinding
rip sk was a good game until devs did something i didn't like

On a serious note, though, much of what you've suggested makes at least a little sense. However, just because it isn't in the game or suitable to your wants for additions doesn't make it a bad game on the whole.

The developers have a reputation of being quirky and off-schedule. Not really a terrible thing as long as it's on their own terms, though, but there are some changes that could be reverted.
Everything that's been added recently has been fun or at least a crown sink people were willing to fill, though, so there's no faulting them for development at the present.

Far as what's being addressed in the linked post, I'll run down the list:

Forge mechanics are meant to slow players down. The old heat system was balanced by not being able to use elevators freely; removal of the forge would mean grinding the Citadel for maybe a week, and bam. Everything's lv10 without pretty much any effort.

Revival mechanics I can agree with, and changes to those have been discussed in the forums many times over. However, keep in mind that the Emergency Revive balances that out a small bit; 2010 was far less forgiving to players in terms of how good at PvE you had to become.

Concerning Shard Bombs, invincitinks need to die. And yes, they are very underwhelming with their performance. There are a handful of broken weapons in the game, and shard bombs are up there.

Key prices are fine where they're at. Though perhaps lower-tier Keys should be added that cost less but yield less expensive items from lockboxes.

Overall bomb damage should be buffed; you're correct on that. The way bombs work in Spiral Knights is an oddity, as they deal less damage than a sword in the time it takes to charge/place them. Even with CTR reduction, damage output is about the same as a single sword-slash. I say this with a disclaimer, however; the area damage that bombs deal is enormous compared to single-point damage of swords, thereby catching more foes in the blast. The collective damage output of a full appropriate-star sword combo would be about as high as bomb damage should reach

The Prize Wheel could use slightly higher rewards, but only in deeper Tiers. Further, you can't ask too much from a wheel you get at the end of every level. It's common/free stuff.

Shields that give bomb/gun boosts would be interesting, like the Mortafire shield/etc. The only flaw there is that you don't actually use a shield while gunning, and bombs just push enemies back most of the time. I'd say at maximum they'd have to be a 3* gimmick like Swiftstrike.

Dual wielding swords? Sure, if you tweaked shield mechanics a little. Dual wielding guns would get kind of sticky when you're looking at controls. How would you shield? With two guns it's somewhat impossible. Dual-wielding bombs would yield an impressive damage output, but again, there's no way to shield, plus the fact that certain types would't work together (shivermist/agni, Nitro/Graviton, etc)

So again, everything you've said makes at least a little sense. However, the perspective of game balance/universal functionality needs to be utilized when you suggest changes like pricing, RNG, or mechanics that might look good at face value but break when applied (such as dual guns)

Because being a veteran player makes you more knowledgeable. Somehow.
