Fel CS and power scrolls were here (long, long, LONG) before the pet revamp. So far, none of the reasons you've listed are enough to counteract that simple point.
I'll entertain you and go point by point.
--PS before the revamp were for toons, player characters. They were kind of end-game item, and prized. Then. - Yup. And now they're for people's toons and their pets. What's the problem? Still end-game item, and still prized. If nothing else, the pet revamp has increased the popularity of spawns and scrolls, and increased the prices. Again, its not required to scroll your pet, you just think it is.
--Now since the pet revamp they are far beyond that : They are a commodity, much more needed by a LOT of people, and not for toons, but for PETS of all things! Their prices continue to be very very high and not very well tolerated even 1 year after the revamp. And yes 50-100 M for just configuring a pet is a lot of UO gold, for people that don't have the luxury of farming gold in UO 20-50 hours/week, and also have real lives and jobs. - So? It is a lot of gold, I agree. Maybe do your own spawns buttercup. Sell what you don't want, and buy what you do. Side note, you could theoretically farm lvl 1 spawns until they bump, get the 105s and eventually roll them up.
--What was the idea of putting out a "pet revamp" and using white PS that are used for players, and making it clear you need to get PK'ed or risk that, lose time and effort just to scroll pets? - .. uhh the Devs? Again, scrolls were introduced as a way of improving characters/pets, but the method of doing it was risky, hence why they're in fel.
--PKing at PS spawn sites in Fel is counterproductive to game improvement. Making people NOT to go there and access the content there cannot be helping the game in any way. Instead it helps the RMT web stores, and the PKers, that are not by any stretch of the imagination the majority of people in the game. - Disagree. You're ignoring that some people play this game for the pvp. I'm sorry that is disappointing. Its also the very nature of a sandbox MMO; people can do anything. There are people who are attracted to this. There's absolutely no reason to not go to Fel. Again, dying is not the end of the world.
--PKing at PS spawns..What other purpose does it have other than discourage and keep players away from content now that we have the "pet revamp"? What benefit is that to the game? Who does it benefit? Not UO, unless the dev team is part of the RMT system plaguing UO. - Uhh so tamers are the center of the game? I suppose that's always been true, but still, that's an extremely self centered view to take. UO benefits by maintaining the heritage its had since its inception. Most pvp players I know who crash spawns (usually mine) don't do it for the scrolls, they do it for the pvp. And there is no other pvp outlet in the game that attracts other players (don't make me laugh by pointing out VvV).
--Looking at it objectively from a game development perspective, PKing at PET PS spawns needs a revamp of it own. Make it so that at least one of the PS spawns has NO PKing allowed. Put a guard system there like in towns. Perhaps in the Piper spawn? That is the easiest and fastest spawn for new people also. Or something like that. It does not take any programming and the mechanics are there : Called "guards". Allow people to get their PS, then chase them for the PS, but provide some relative means of escape. - I have no counter to this because it is simply asinine. See all other comments. As for no escape; uhh run? Not hard.
--It is NOT the PKers alone that are to blame alone for this. They enjoy playing SCUMBAG role for fun and profit, and likely RMT profit ultimately. Most importantly it is the DEVS, with their exceptionally poor fore sight, and 100% hind sight, for not predicting what happened, and not having provided OTHER means of upgrading pets. - Scumbag? Sure. Sandbox MMO? Yup. Be good, be evil. Welcome to UO. There's the door if you don't like it. I believe the Dev team was foresighted enough to realize that this would increase demand on PS and deliberately left the system unchanged.
--Lies, half-truths, excuses, personal BS anecdotes will not help with this, and all the arguments presented by PKers are BS. We need just real arguments, remembering that this is not any longer AOS, it is now 2018, and that there is such a thing as "pet revamp", and pets eating scrolls at a rate never before encountered in this game, and with still sky high prices. - I'm still waiting for you (or someone else) to provide real arguments for moving them.
--Most normal people would like to go to PS farming with their friends themselves, they would rather NOT buy the PS RMT or vendor, enjoy getting them, and not get PKed and Griefed while doing that. - Then do it? What's stopping you? Death? I can get a spawn off any day of the week without a single person crashing. 2 people can do a spawn in a half hour. 4 in about 20.
--Grow some B*LLS and see reality for what it is buttercup: If you are a PKer at spawns you are a SCUMBAG, and you are contributing to the demise of this game one way or another, whether you are the RMT "Avatar 1,2,3,4" advertiser in game, or just a lousy low-life griefer. - You said it best "Grow some B*LLS and see reality for what it is buttercup." Nothing more to say here.
--It is ONE YEAR already people. Open your eyes and see reality. - See above.
--Yes no big deal getting PKed at the spawns. Does it make it right? Do the PKing ELSEWHERE. Try to PK the mining farmers or other people that come to PK land for other content. - PK elsewhere would happen if people where elsewhere.
