I pretty much like the concept of Ancient shadows, but there are still some major issues I have with it.
Balance mostly, but that should eventually be doable.
It feels to me like a lot of the scenarios require a certain loadout to be beatable in any reasonable manner or beatable at all. The colony ship one in particular.
I havn't found any other way but carrier type modules (Bomber, fighter...) to be of any major use here.
I found that scenario with a cruiser hull, not sure how many I did before though.
The ships came at 2 to 4 second intervalls with 16 spawing with each wave. It's absolutely impossible to do that with a lot of cheese or luck.
Another thing in general is, that once you die in one of the further out nebulas, the scenario is pretty much done. The champion becomes such a large factor in time when the scenarios scale up, his absence is almost an instaloss.
So, the fact that certain weapon loadouts higly favor certain scenarios and the loss of the champion is almost certain defeat and the need for cheese, in the current balance, lurks at every corner made me thinking of ways to solve this without major finetuning every single scenario. It's okay some are harder, some are not. So:
1.
Allied main starbases get the ability to repair the champion and rebuild it's modules at a reasonable rate.
No more need to cheese and see what's in there, reload and fly in with an appropriate champion setup. No need to place engineers outside, no need for a lot of rather annoying stuff.
More tactical depth, as you have a place to retreat to and maybe even change your loadout mid scenario to adapt to a changed battlefield.
2.
Speedboost ability.
Available from the start, just like the shield.
Double movement speed for a short time (Couple of seconds)
This may even only be usable within Nebulas, as the champion already is pretty fast outside.
Brings more action, brings more satisfaction, gives more choices than shieldspam and wait til the energy is up again in the scenarios. Basically a secong ability you want to do all the time, but can't.
So, for me these two pretty much nail it.
The champion on the outside is fine as he is for me and inside the nebulas, those two changes above should completly do the trick
