I know, I know, I'm a mad man. Hear me out!
Grappling Struts are a lot of fun, and they are integral to the character of the Vulture Droid. After playing a few rounds with Vulture Droids, however, it seems clear that while fun and characterful, they aren't worth the points.
It is extremely difficult to place multiple Vulture Droids on one object, they are countered hard by the opponent placing nebulas, and making the decision to use them deliberately comes at the cost of signalling to your opponent where you are going to be for a turn or two.
Obviously, they have a lot of value in that they allow you to use objects as cover if you grapple onto them so that the enemy ship has to draw line of fire through the object to you. Additionally they allow you to safely overlap obstacles to keep your action (and not take damage or stress).
Given the limitations placed onto your maneuver dial though (while the 90 degree turn can be considered a very good thing, maneuvers that aren't a turn or a straight 2 or a barrel roll are completely ignored) simply landing on an object for a turn seriously telegraphs to your opponent the very small amount of places you can be the next turn or two.
Much like the configuration of the X-Wing, grappling struts are a part of the character and should be a part of the playstyle of the vulture droid without paying additional cost onto an already arguably overcosted swarm ship (though that is a discussion for another day). If not a free upgrade, then at least a points reduction from the currently very expensive 3 points per droid (adds up when you have a lot of these guys, which you do).
I'd love to hear your thoughts.
