Welcome to the suggestions subforum, where we tell you your thoughts are meh and unoriginal!

Nah I'm just being silly. But there is a bit of truth to that comment - bringing back sleep is a suggestion that comes around every so often. The sleep status on knights is sort of broken and glitchy at the moment, so most of us would prefer a revamp to the status before we see its level set come back.
Additionally if those levels are brought back we'd need to have arsenal stations added to the start of them. A glitch in the system post battle sprites was that we had the shrine of slumber show up in the random gate rotation, but it wasn't updated at all since it was removed. They removed it again after noticing the mistake.

As for bows, that's another suggestion that's been thrown out before. One big "no-no" for weapons is removing your shield for any reason because shields are critical to high level play. Almost all "dual wielding" suggestions say "more weapon, less shield!", but fail to understand the fundamentals behind the shield's place in the game.
On top of that, an ammo system is meh.

When creating a new weapon type, it's always a good idea to ask yourself "could the same thing be done with one of our weapon types as is?". More often than not, yes, it is. People have called for throwing knifes when we could have them be a dagger melee weapon with a ranged charge attacks. The bow you suggest is essentially a magnus with no shield plus an ammo system on top of it that isn't like anything else we have in the game.

As it stands, sleep is just a cheaper version of freeze. Once inflicted, you are immobile, unable to attack or do anything until it wears off, and heal at like, half a heart per second after 2 seconds. The animation is buggy (playing the /sleep animation, but constantly trying to activate it, making the player twitch awkwardly).

Plenty of changes have been suggested for making sleep more well, interesting. My favorite suggestions have been:

• You knight becomes drowsy, and is on a timer before actually falling asleep. Movement is slowed while drowsy.
• When you lose a certain percentage of health, you will immediately wake up from sleep and be immune to sleep for X seconds.
• While asleep, you can mash the attack button to wake yourself up quicker. If you wake up via this method you will be slowed and not heal from being asleep.
• Friendly knights can pick up knights who have fallen asleep like a statue, moving them out of danger until they wake up.

Plenty of ways to make sleep more of a status that's not just "freeze - the annoying version". Even if they kept the status the same was as before, the animation being buggy needs to be fixed.

I just died at the 'friendly knights can pick up sleeping knights' idea. The mental image. I CAN'T STOP, MY SIDES.

Even better: The /sleep command in dungeons inflicts a less-severe sleep status on users, that can wake up by simply moving around.
This method does not grant healing, but still allows the player to be carried around

Shrine of slumber wasn't all that exciting tbh. It's pretty much just a lichenous lair with sleep and enemies that can't merge.

The bow is still sort of meh. Making "one weapon that's better than everything else" is sort of a problem. It's not a problem because it's dealing so much damage, but in the same amount of time that you'd be waiting to fight again you could have charged 6 brandishes, done 20 hammer dashes, swung 18 times with a sealed sword, etc. When you limit the combat effectiveness of a weapon, all other weapons will outclass it. When you make a new power weapon, it outclasses everything. You're trying to put both on one weapon when it should just be designed like any one weapon instead of some new fabled thing.

Also I'm glad people liked that sleep idea. I've been sleep deprived lately and just sort of pulled that out of my brain because I wanted another example.

tier 4 is a terrible idea. to not make gear horribly unbalanced by giving just a few items 6* and 7* variants, you would have to give pretty much all gear 6* and 7* variants. do you know how much gear there is in the game?
also, you would make people craft up all their current items. this would disrupt the economy to a terrible degree. also, upgrading would be insanely expensive under current rules. first you need 453 radiants to heat to lvl 10, then you need 6* orbs which would cost double of 5* orbs, then you need a couple hundred 6* fire crystals and 7* orbs, which would cost even more, quadruple of 5* orbs and then you need probably thousands of 7* fire crystals, which would be even rarer than radiants and even more expensive. that would be upwards of fifteen bucks PER ITEM only from orb costs.
if you instead nerf 5* item cost, you are gonna piss off a LOT of vanguards , you know, the people that still play despite the lack of content.

Neueragon pretty much parroted everything I have to say about a "tier 4". In this case, "more" is not necessarily "better". Look at the gunner update and tell me that the "more is better" attitude made it better or worse.
