Every! hyper jump atm Drops you at a star, dropping out of Jump space every time at a given point provides a choke point in every system groups of raiders stationed there with some strung out along the most obvious vectors in system ready to interdict add to that another fixed point the destination station where others await to interdict, and you would end up running a gauntlet, unless you are part of the group. thus a system can be blockaded
It drops you at a star, but at random locations. Given the distance scale involved, a far cry from being dropped in a fixed sphere 10-12km across, like you get in Eve.
So for example, an evasive maneuver would be easily performed immediately post-hyperspace. Drop out of supercruise, full throttle, boost, vent heat and go cold.
Even if anyone is precise and fast enough to drop near your location, they will have a very hard time picking you up from the stars.
*Especially* if you, as you should if you're intent on evasion, pick black decal camo for your ship paint. Might as well be invisible.
System blockades, a.k.a. camping, rely on players being forced through chokepoints. The only chokepoint currently is the station entrance. But that's a bad kind of chokepoint. Eve gates are much better since if you sit at them, you control the system. If you sit in front of a station, you just control that station.
I expect, instead, that tactics will involve active, fast system sweeps - a number of groups will hyperspace in a system and look for signatures; mission runners in combat, supercruising ships and the like. Unattentive people will likely either not have proper scanning gear equipped or will not pay attention to their ship scanner to notice a dozen new signatures flaring up. That's going to be their meat.
But I seriously doubt they could sit at a few key systems and just catch people in a net, or at worst deny access to anything but that system.
In other words, lots of
fun, not boring camping and not being forced to log or lose the ship.
