So, first off, I don't play Elite anymore - console player that uninstalled after EDO launched - but I want to give my feedback because, well, engineering is a major part of why I quit playing. EDH is great and still ran fine (at the time) on PS4...but engineering...it just stinks. So I'm glad to see you guys finally looking at it.
Right, the feedback:
1) Material Grinding via Missions: Rewards for all levels of materials are too low and not nearly common enough in mission rewards. I would gladly trade credits, influence, or other rewards for meaningful gains in materials. Not 3 to 5. More like ten to fifteen. Put another way, if I take a mission reward for materials - G1 through G5 - I want that reward to encompass at least two or three rolls for a recipe where that is the highest demanded material.
Scale them with mission difficulty by all means: for low ranked missions, the current reward paradigm works. For dangerous and elite missions? The materials gained need to match the credits gained. It's ok if they are a standalone reward, too, as in no reputation or anything...just the materials.
2) Material Grinding via Open World: I'll echo the common sentiment that it would be nice if a broader range of materials were available in all activities. That said, I don't expect a Thargoid to drop Heat Vanes or what have you. Rather, I expect material rewards in missions associated with all playstyles - deep space passengers/exploring to trade missions to combat missions. Beyond that, I generally find open world grinding mostly ok...just that materials tied to the BGS make little sense since, well, the BGS itself makes little sense. It is poorly explained in game and I think that frustrates new players as much as veterans that would rather not google it up. Especially on console where doing do is even more of a chore.
3) Engineer rolls and advancement: I think the guaranteed progress was a huge improvement over the original system and don't want to see that changed. I do think the current system can sometimes be punishing, BUT, that has more to do with material grinding than a guaranteed improvement. It's only really noticeable in those final 'top offs' where you've obviously programmed the game to just devour materials for that last %. Which sucks. Don't do that.
A guaranteed material bracket per grade sounds nice, but at the same time seems like it will only further incent material grinding to a point. I wouldn't do that, personally. I think if you solve the material acquisition loop, the existing format for rolling improvements will seem far more benign. Maybe balance that last % or two in your algorithm, but otherwise it all seems fine to me when I have the materials.
4) BALANCING ENGINEERING: This is the big one. No, I'm not going to pretend to know how to balance it. Only that it does need it. Engineering has become a run-away god mode in a game whose title literally includes the word "Dangerous". Reel it back in. A LOT. To be more precise, I want to see my Vette getting roughed up more. I want to see Thargoid difficulty permeating most of the game because that is fun, but you can't do that without first fixing engineering so you have a baseline.
Beyond that, I'll echo other sentiments: engineering should be about crafting a unique blend of your ship. Which is to say it should reflect your ethos towards combat, defense, trade, exploration...engineering is 95% combat. That's a real let down.
Additionally, as part of making my ship...it means those choices should have consequences. Super unpopular idea here: the negatives of engineering should match the positives. Wanna jump further? No problem, but it's gonn eat fuel like a beast. Want crazy strong shields? Cool, except not because they run super hot. Want death lasers? Covered, expect lots of death from them overloading, though, too. Engineering shouldn't be a "get stronger, power creep" feature. It should be a "make choices and embrace the opportunities and challenges they present".
Please, please, please rebalance engineering. Not just for combat, either. As a huge exploration fan it kills me that engineering offers almost nothing of actual significance. There is not one engineering recipe that meaningfully changes how I explore. Nevermind how I trade. FIX THAT and I'll come back just for EDH alone.
