I have not yet tried Vorton Projectors on wormholes, but from what I can tell the trick is to make their damage bounce towards any frigate/shuttle/pod that comes out of the hole, instantly and without the need to lock those ships up. So in the 2 seconds it takes to align from gatecloak to warp they can be hurt.
Now I don’t know if the damage applies for the full 2 seconds or for only 1 second until they’re in warp, but I’ll assume it’s the worst case of 2 seconds (unless someone can correct me).
- A Skybreaker (with max dps fit) deals about 116 dps with volleys of 480.
- A shuttle has about 800 EHP
With good timing, only two Skybreakers are needed to kill a shuttle.
If the Skybreakers are continuously shooting the wormhole (and their attack cycles are evenly spread!) you would need 4 Skybreakers* to consistently kill any shuttle coming through the hole. And a few ships extra to cover eachothers reload cycles. This doesn’t seem hard to do, which is why people do it I guess.
*(Or 8 in case damage only applies for 1 second rather than 2).
Now take an interceptor with 16 times the EHP versus Vorton damage types as the shuttle. You will now require 4x16= 64 Skybreakers (or 128 in case damage only applies for 1 second rather than 2) to keep people from coming in.
I’m not very experienced in wormhole space warfare, but I don’t think you have that many ships camping the wormhole 24/7. And if you do, I don’t think it’s unfair that it’s hard to run through a wormhole that has that many people camping it.
