As of U23 with the new level cap increase to 120, seals no longer drop from instances and since Essence Removal Scrolls cost 1 seal per scroll, this effectively removes the option to buy these scrolls from the Skirmish Camp Curiosities vendor.
Now on Bullroarer, we have this new window when you try to remove essences.
Since the means to obtain seals cuts off the means to obtain Essence Removal Scrolls, this system is basically forcing the player to get Mithril Coins from the store if they have no seals in their wallet. Either remove the seal requirement to barter for these scrolls from the Skirmish Camp, or make seals drop in instances again. The first option is better in my opinion.
I'm certain that majority of players are against this change because come on, 1 MC to remove 1 essence from 1 piece of essence gear? That is so ridiculous. The option to use Mithril Coins should not replace the free alternative that is already in-game, both options should be available to the player otherwise this just becomes P2W.
Like it is so convenient that this was left out of any patch notes, nice stealth change, well played. It is clear that every player is wearing the low tier yellow or purple essences and they have to upgrade sooner or later, so this was put in place to make money off of changing gear of all things.
P.S. I know there is going to be at least 1 person who will say that it is easy to grind out LP in the starter zones so anything P2W doesn't matter. If you are that person, do everyone else a favor and just don't reply here.
