I am speculative if the new capture point ranges will make much of a difference. The requirements for plexers are now to pulse d-scan at the gate entrance vector. As soon as anything shows up, warp off.
Presumably career plexers were already doing this, but...
360 short scanning the accel gate into a plex is pretty much SOP. What the changes mean is that you will always need at least one person on the timer within scram range and prevents what at times happens now in which people won't engage because they have to consider burning 80km under npc fire before they can even get a point on a target.
It might not change much in tactics because people will probably do the same as now and just have tacklers on the warp-in/timer and have long range ships setup off it to blap anything that comes inside.
Also, def. plexing alts are mostly brain dead and the only thing that saves them currently is the fact they have time when alt-tabbed out on a timer to warp off due to the distance involved. With the changes, it means even if they're stabbed they can at least get caught with a double scram ship on the warp-in/timer if they're not spamming their d-scan.
