Yes, I noticed that distributing power to shields and weapons works good, though I keep switching and am trying to get better at it. It makes quite a difference when I can switch full or more power to shields when being hit and switching back to weapons when I'm firing. I don't boost much and it's good to be able to boost when having to run.
If I had bi-weave shields, they would be gone in no time. They can't take much and they would have to recharge like 5 or 10 times as fast as they do before they could make up for it, and then you still need the energy to keep them recharging. Perhaps they are feasible when you have only a single enemy at a time and am able to take it down fast before the shields are gone so you have time to reload before fighting the next one. That is a very limited application, and it means you are much more likely to take hull damage and that you have to run away a lot more to give the shields time to recharge and you have to keep running for repairs most of the time because your shields are gone. "Normal" shields take ages to load, but they allow me to shoot down some enemies before they are gone and to wait after that while I'm picking up the materials. So overall, be-weave shields are basically like not having shields at all.
But that's not what I mean at all. All the medium and large ships I tried are painfully sluggish (and I don't want to use small ships for anything because they are not sufficiently versatile and too brittle for combat). The Python is a bit better with engineered thrusters, but it still flies like a brick going through melasses. I wouldn't use it for combat at all; it takes only a few seconds to get shot down in it because it's so slow to turn that you can't even hit the attacker MOTT. The Python is a freighter, and it remains a freighter. The Anaconda is worse of the same; I left one behind in a shipyard somewhere half a year ago because the insurance is so expensive and a Type-9 has more cargo and is a lot cheaper, and I'll probably just sell it. Even transferring it to my home base or anywhere else is so expensive that I never did it, and I haven't found a use for it.
The Krait is the only ship so far I have been able to do any combat with successfully. And it's only possible with a lot of engineering. I don't know how Elite Dangerous was before there was Engineering, but I think it's not reasonably playable at all without now. It's too limited and no fun without.
They also should invent a new jump drive that gives us a minimum of about 75ly jump range and more for more capable ships. The universe nowadays is a lot bigger than it was in the previous games.
