So I finally did my first hack (advanced research redirect hack, first hack of the game) with the new system (our usual Trio of players). Unfortunately I also had the Shark B plot on. We found out Shark B in 3 player multiplayer at 230 AIP with hybrids and advanced hybrids on (4 and 2 severity respectively) means any planet loss means you have to savescum (whee).
Basically what came about for us were all the waves that people are complaining about, which I agree that there's a problem with the AI response being solely based on the AIP when you haven't hacked much but that's not really my problem.
My problem with hacking response was they were doing 4-5 deep counterattacks with _30_ seconds warning. This is completely unfair on just about every level, especially when you have the Shark plot on. Normal counterattacks are 9 minutes warning, and normal waves are 3ish.. Why are the hacking normal waves 2 minutes warning and the counterattacks 30 seconds?
At the least, this should be reversed. There should never be such a thing as a 30 second counterattack, that's just cheap and there's literally no way to prepare for it. We had to pause the game, build like 20 engineers each and ring the command stations (which were also largely mil 3 so it's not like they were defenseless..) with gravity turrets and pray we bought enough time for somebody's fleet to free up to attack.
That said, I really like the concept of the new hacking, but if it remains at 30s counterattacks apparently anywhere it completely destroys our playstyle and we'll basically never hack. Without Shark B on we could probably live through it but it's just too annoying to be useful, especially given how many waves they deploy in multiplayer.
