I didn't see mention of Forma Blueprints being fixed from Acrithis' Shop. However in the event they've still been overlooked: Attempting to purchase 10x Forma Blueprint from Acrithis' Shop will consume 10 Parthos Clamps but not give the player 10x Forma Blueprints or 10x Formas. It gives neither, it consumes your Parthos Clamps and gives nothing in return. Whether in the Duviri Paradox after the Oroworm is slain or in the Dormizone's shop. Recommendation from an afflicted Tenno is to remove Forma Blueprints from Acrithis' shop until fix, in hopes of preventing future victims. This not only removes a bugged item from the shop's pool, it prevents players from being actively scammed.

That is not true, Ability Efficiency used to not be capped, the soft cap was 90% because Streamline gave 30% ability efficiency and Fleeting Expertise gave 60% ability efficiency, the two combined were 190% ability efficiency or a 90% reduction on energy costs. The cap was put in place when they reworked the channelled ability costs in which all abilities efficiency was capped to 175% and duration now factored into ability efficiency calculations.

There is no doubt that a player can use a channelled ability for an extended period of time. Whether Energy Siphon the aura or the focus school Zenurik's Well Spring ability should work with a channelled ability is a different topic. Energy Siphon is arguably strong, however it does give fixed energy generation. How easy it is to access energy for a warframe and how they use their ability is different. What resources it takes to access or utilize various forms of energy generation such as Zenurik's Well Spring. Etc. etc. etc. Abilities aren't free. At least, Digital Extremes does not believe they should be. This is a basic design philosophy that they would like to adopt. And, coming forward, likely abilities will not be free. This topic isn't only in just whether a warframe's channelled ability should be able to use regeneration or if their costs should be decreased more in line with more modern or even more imbalanced but fun frames. When will we debate whether Channelled abilities should be reworked? Likely when enough support in the game is available for channelled abilities that a serious rebalance would need to be considered. We are beginning to see new arcanes such as Arcane intention, at rank 5 able to give 250 max health per channelled ability. There is Braton Incarnon that gets 38 base damage with a channelled ability active or Kunai Incarnon with 100% multishot. These are small ripples as of right now, but likely they will come to form large waves. Warframe's energy economy will likely become a future topic point, however in personal opinion, the topic of energy generation will likely be in the topic of a "nerf" and a overall restructuring of the abilities we call "Channelled" abilities, with greater energy drains and lesser effects, unless a creative solution is found.

Energy Generation has long been disabled for channelled abilities, if they weren't many abilities could be kept active indefinitely. Energy Generation has been available for channelled abilities in the past, this was changed to disable that possibility. I.E. back when ability efficiency could reach 90% and Excalibur could use his Exalted Blade for however long he wanted. Some variants utilized energy regeneration from energy siphon aura with the blind rage corrupted mod balancing efficiency for damage. Now, Excalibur wasn't the only offender of using Energy Regeneration, but he was one of the most popular at the time. Is it possible to keep a channelled ability active indefinitely as of current(?) to a degree yes, through helminth energy orb pickup bonuses or arcane energize, the ability to gain energy and outweigh energy loss is possible. However, Energy Regeneration as in forms such as energy siphon were deemed too powerful or too easy to manipulate to obtain effective energy income for channelled abilities. This could become a topic for further review, but that is not likely in the near foreseeable future. (And, likely the topic would be in a rebalance of channelled abilities reducing their efficacy in turn for easier upkeep, making them even worse)

It's not the best purchase, it is a permanent blueprint but the production rate is too slow to really get great value out of. And, it costs quite a sum of other resources. All the resource purchases are terrible investments, with I suppose the cell blueprint not being great but it is maybe better than the one off purchases. At least you can't buy it again. For newer players if you need resources, farming them is the best answer. Albeit, that would cost time. Is it a noob trap? Maybe? I suppose if a newer player were looking for Orokin Cells, this may be what they'd find.
