2. You claimed 40mil/day raiding... An average individual WITHOUT VIP have 10attempts in raiding. (200ep, 10tries) That means that same individual has to be GUARANTEED an energy converter or 4-5 REFINED Frags to make that amount, so unless you are literally the god of rng which I definitely envy you, this number is completely wack.
You forget the free daily Dynamite Power Vitamin Z and 30 min community mat which restores 130 EP, giving you 6 more runs per day. On average I make around 350,000 DZ per run, so 16x 350k = 5.6mil. If you actually complete the side quest, you can get a guaranteed 2x inferior fragment per run which is worth 150k for 2, so 150k x16 = 2.4 mil. 5.6mil + 2.4mil = 8mil at bare minimum per day for a F2P player. That does not include ANY drops from the actual raid itself. If you sell all the loot you obtain I can see people making 20-30mil/day realistically, without having to rely on RNG from the boxes for energy converters.
The fact that your minimum 8mil still relies on RNG to push to 30mil a day is a slight problem. My drop after 20runs today: Inferior: 92, Common: 3, Refined: 0. Given current market prices, that gives me about 15mil in profit today. (20runs is also more)
But lets go with your 30mil figure. As of yesterday morning, the prices were at 2.8mil, as of today morning, the prices are now at 3.4mil. That means within a SINGLE day, your 3attempts a day have now become 2.666tries a day. This isn't going to stop given the current drop rates.
I don't have any data on drops, so I have no clue if your drops fall below average, average, or above average. Without any refined I doubt it would fall into the above average. Is that the total from 10 runs? There are more ways to squeeze out profit if you are really stressed over it. You can equip the Greedy Millionaire title which gives +18% DZ, equip the Scral tier 3 akasha card for an additional 20% DZ. By investing into gold/silver vip you gain 200 more EP per day which is 10 additional runs, 30% DZ bonus, and no market fees for you to sell your loot.
I could go into a lengthy analogy of expected value you have from getting boxes that have a x% drop rate chance of energy converters that you should also factor in, but I don't really have a clue on the % which is the determining factor on the average you would make per day. If x is 0.5%, then you would figure about 7-8mil/day of ev given that you farm 50 boxes a day.
As far as WUC goes, I don't really get why people complain about the price. I play no part in trying to control the market, and I do agree that 3 mil per chip seems costly. Just remember that NO ONE IS FORCING YOU TO BUY WUCs. +6ing a weapon isn't all that difficult. If you are one of the unlucky people that tried 20+ times and failed to upgrade your weapon, you can actually buy a +6 weapon from the market for an affordable price. If you buy non vivacious calling set weapon, such as the weapons dropped from Ark Ship ep4, there are some on the market that are +6 that are under 10mil. All current endgame content can easily be cleared with a +6 weapon. Getting anything above +6 is just a luxury to be able to clear raids faster. Same can be said about the vivacious calling armor. You don't need it to clear current content, you can pretty much wear whatever, you don't even need to +4 armor.
