well, I second the notion that I prefer the old inhibitor.
Logical side, this doesn't make sense. If it blocks jump, then it block jump, a phase lane to your planet or other planet doesn't change the nature of the phase lane. I can understand if they are connect by gates, but they are not.
Also agree that this can be classified as a simplification and it does take quite a bit out of strategic decision. Not only it's no longer needed to scout a system before attack, one can just try to jump in and out until the right opportunity arrive.
Another oversight is this: when attack a system with old jump block, not only I need to scout the system before hand to see if my force can deal with defense, I also had to prepare some back up in case they send re-enforcement. With the old block system when thing started to look bad, I have 2 decision to make:
+ Send in more ships to rescue the attacking ships and hopefully take over the system. It's the either win or die trying scenario.
+ If I deem the situation is totally hopeless, I may have to forfeit the attack force and keep save the re-enforcement ships.
With this new jump blocker obviosly this decision maker isn't really needed, I probably don't even need back up as I can always withdraw if the situation become desperate. I mean, no matter how well one prepare, attacking a well defense system is a gamble, one that you can certainly lose, the new jump kinda take the risk element out of that.
And
Hit and Run anyone? Jump in, cause maximum damage and high tail out of system before the opponent react? I'm 101% sure that tactic going to be exploited both in online and off line play, it's too tempting to say the least, quite cheesy like macraroni too. While it's true that the inhibetor is to prevent incursion, I also think prevent riad like this is one of its legitimate function.
I don't think this gonna help the AI (if it was an intention) because from some angle, it hurts the AI more then it help the AI. If you're talking about MP balance, then some frustration and tactic are being trade off for that balance.
