So many things to touch on so little time. You ignored my results the RNG and jumped to something else. Let me ask you this. You mention moonstones, they give you the option to get them from doing battlegrounds, you get them in rng / small amounts from the daily and weekly challenge chests. Could the amount be better? Sure buddy! They gave you some more sources for the crystals. Upgrading your gear cost crystals. Also prices adjust due to the amount of supplies on market. If less people are selling the materials in order to transmute a item of course the item in question will raise in price. Marketing 101.
Now them giving out the stage 11 soul / pet aura. Did it really screw out older players all that much? I mean before the change to a 5 stage system, they only saved 10 stages and maybe 1 event worth of pet pods. However it was to help 'newer players' catch up to a very low point much like the weapon upgrade / accessory upgrade events. Could they of handled your example of the energy > powder thing better sure, but at least you got some sort of gold returned. So they tried to make some kind of amends to it.
I've looked at F10 and honestly all I see trove is included is pay 2 progress. While we / you might not like to admit what they are doing currently while it may look like pay 2 win, is more of a grey area. "No paywalls will hold you back, and no amount of money will give you an unfair competitive advantage over other players. We don’t like pay-to-win, so what we are offering are cosmetics, convenience, and consumables – not power, not gear, not permanent stat increases." Pay walls do not hold anyone back, grant it the time frame for the amount of effort might make some think otherwise..Everyone is able to get the same items as everyone else just the time frame is vastly different.
Anyways, I'm going to go get my breakfast, was a fun read Merlin but in the end I still say, nothing in this game requires end game gear in order to do unless your speaking about raids which honestly should since they are to be harder content, however to enjoy the game and to progress you honestly do not need to rush everything and be at the max gear when the new tier is released on day 1. If you feel you 'must' be at that level in gear then you have the option to pay money for a shortcut. It is a option but not required.
