True for the less experienced of players on the lower tiers having only 100 mist energy was sort of a problem, but easily on tiers 2 and 3 a player could earn enough crowns to buy more energy and thereby keep on going, and the process would continue, It does seem a bit repetitive and that's why I am not necessarily against free elevators, I merely meant to address the fact that it did increase the prices in energy.
Also before I forget, I personally, not sure about everyone else, dislike how there is a restriction on equip able items for players based on their Rank (apprectice, elite, vanguard, etc.).
Does nobody know you can buy 10 Sparks for 200 Energy from the Supply Dept. while in Haven? Your post seems to largely neglect that the Supply Dept. has energy trades for various rarities (and in fact I believe the prices for 3 of a given orb are equal to the original energy cost to craft).
(I also will say that I am happy to see most of the systems added with the removal of Mist Energy be reverted, but without free elevators there's not much to do since you'll do a few levels and then just have to wait until the next day, which is rather a bother. Really I think the true solution behind rarities is to just increase their drop rates so that you don't have to be on Elite to have as much as a slim chance of getting any.)
