Who cares about pixels gold.. you complete all grind quests and u will have more gold after all than 7,75b... Problem is time gated for this time gated quest which are nouvers scale .. give me quest where I can pay 20-25b fo heart one time and get it instantly after saving enough silver .. Secondly this 7,75b is nothing .. because u still need 8 months to complete dumb Nouver chapter ..

But they want for 9b, not 50b.

Look at eg. lightstone of fire strike. With each increase in the maximum price, the number of bidders decreased until it fell to zero. Not only were there no more preorders but these lightstones were in stock.

And it will be the same with garmoth heart because player only needs one so he will just force himself and do these quests.

Same as I forced myself and did alechemy guru1 to purify lightstones for half the price.

Well, I didn't say any price in particular, you just made that assumption on your own.

And I'm absolutely glad they increased the cap on those lightstones... I had to open over 300 fire lightstones only to get the cheap ones because there was no way you could get one from the market at such low prices.. At least I was able to get my hands on a strike lightstone right after they increased the cap. It's better for me that way instead on wasting silver popping purified lightstones. Besides, those lightstones dont have many preorders going on at this point not because of the price, but because of the fact that they are unbreakable. Meaning that if you got enough for your builds you don't need to get any more. I'm willing to bet that once they increase the cap, people will be more willing to actually start selling any spare hearts that they might have.

Besides, at this state a lot of people are even reluctant to sell it because if they do and they regret their choice later, it will be extremely hard for them to reobtain it. So it would only make sense to keep the heart on warehouse in case they ever need one.

Honestly, PA should have you collect a couple of Karanda Hearts and Kutum Hearts, take them to someone and combine them into a non-sellable Garmoth Heart. Literally only 2 or 3 Karanda hearts + 2 or 3 Kutum hearts, these are still rare. However, they are not even side-grades, they're just straight up inferior to Garm's heart. Also, people really don't like coming to Thundercloud Kutum.

This

there are so many preorders it's only because it's accessible
players don't even consider kutum/karanda because for only 9b you have much better
and also because kutum / karanda if you put them in your weapons and you have them caphras, it will cost you several billion to remove this crap because of the cost of the extraction of the caphras

I stopped attending Garmoth long ago, because it just feels pointless. 
Meanwhile got 2 Karanda Hearts.

Got mad lucky with a pre-order I even forgot I had, my 9.1 billions were sitting there for longer than I can fathom, but this was last year that I got it. Fortunately, due to this luck, I just cancelled my 2nd pre-order of the garmoth heart cause, it's pointless nowadays with this many pre-orders, it's been 6 months, I've just started the questline to get the guaranteed garmoth and that'll be it, Turos and stuff is easy, the problem are those nouver scales and concentrated black stones (can easily get them through lifeskilling fortunately, or well, the materials anyway), but at least I know I'll get it eventually in a few months...probably.

Karanda and Kutum is less rare ? I dropped Gamroth heart finished pity questline never seen karanda's or kutum heart I do everyboss each day in the evening hours xd

Wanna fix the Garmoth Heart availablity problem?  Make the max price worth selling.  Right now I have boss alts with Garmoth hearts on their weapons because they are not worth selling.  I currently have 9, if the price went to 25 or 30b I would consider selling some of mine.

increase max price to 20b and the hoarders will start listing theirs
